This article will study in depth the examples of heterotrophs and why they are important. Of the grouping of creatures and types of living microorganisms; photoheterotrophs and chemoheterotrophs, their attributes, origin, idea of heterotrophic feeding, digestion, as well as including different, drawings and models for optimal understanding.
Why are they called heterotrophic organisms?
When entering the field of biology, one can understand how significant it is, to see how unique living entities are sustained. Here comes the scrutiny of digestion, what are the means and responses produced by the change of matter in these living entities.
That is why it is possible to enter the field of digestion, to refer to the type of complement that is obtained, also recognizing the two elemental ways that characterize the species that have life; heterotrophic and autotrophic creatures, which together make up all current life in any territory and biological system on Earth.
Remember that the metabolic media and the imperative nutritional elements of the life forms that reach to reveal themselves in various types of biological methods, which in turn require vitality and fixed carbon to incorporate and frame their cells, are considered.
Realizing that all living animals require a certain type of food, in case heterotrophic methods are found out; The importance of Hetero is characterized as others and Trophies, food, so the idea of the word incorporates every living being that does not make its own food and needs to benefit from others, very important examples of food chains to complete the life cycle.
That is why we are facing the investigation of heterotrophic subsistence and its attributes. For a superior understanding and a better light in the observation of where we will be, a small design is left to them as examples of heterotrophs:
Furthermore, to make a better review, you are given the opportunity to view a table that orders each living species as indicated by the five kingdoms and their relationship to the type of sustenance:
What are heterotrophic living beings?
A heterotroph in biology is a life form that does not make its own food by carbon fixation and in this sense, obtains its consumption from supplements of various natural carbon sources, basically plant or animal matter.
The heterotrophic feeding process envelops each of those living entities that consolidate the natural matter previously made by different forms of life on Earth (they are not equipped to frame it from basic inorganic substances).
Since heterotrophs are recognized, you will now need to perceive what they are in a general way: really all creatures (from well-developed creatures, fish and winged creatures), algae, microbes and most bacteria would also be incorporated.
Examples of heterotrophic beings
We get among the examples of heterotrophs all the creatures that make it up: bacteria and a very large number of unicellular living entities. Some examples can be offered for this:
Count up the huge feline predators
Among them the tiger, cheetah, cats, lion, jaguar, panther, have a very specific diet because they are carnivorous animals, they are dedicated to hunting chasing different creatures, mostly herbivores of good size.
Mammal ocean fish and animals
From shark to sardine, tuna to dolphin, life in the ocean is a constant way of eating or being eaten. Here you can see the type of nutrition used by the big fish that love to eat the little fish as well as natural production, so they sustain themselves on small crustaceans or tiny fish.
In its entirety are the fungi
Although they don't look that way, fungi are examples of heterotrophs, somewhere between a creature and a plant. They have bodily structures like the plant kingdom (ie, cells with cell dividers), but are sustained by decaying natural matter: wood, paint, humus-rich soils, and even the host of other living creatures.
The incomparable African herbivores
It is made up of huge creatures and herbivorous sustenance, for example, the beautiful gazelles, the elephants, the incredible giraffes, the impressive rhinos, and others, which are often prey to huge predators.
protozoa
They are the tiny, single-celled life forms found in humid conditions and maritime situations or within the environment of creatures that they sometimes parasitize. They sustain themselves by engulfing other living cells to consolidate them in their body or by retaining supplements through their cell layer. They are considered semi-heterotrophic or semi-autotrophic, depending on the species.
People
As examples of heterotroph, you can get it in the feeding routine followed by human beings, who make a very consistent combination by mixing the nutrients of plants and creatures as well as those that arise from different living creatures.
certain bacteria
The kingdom of microscopic organisms is gigantic and diverse, incorporating some autotrophic genera (photosynthetic or chemosynthetic) and different heterotrophs, for example, those that attack our body in case of contamination. It is noteworthy that, these microbes feed on our own cells and tissues, everything is a chain.
the field of arachnids
The most impressive critters are obtained, made up of the terrifying scorpions and the amazing centipedes, they are the most fearsome predatory animals in the world of arthropods. They are insects, where each one of them has developed its procedures to catch their prey, whose internal fluids they feed on.
Classification heterotrophic beings
These entities can be classified from numerous points of view, they are of great importance and are of great interest, however the most significant are those that are shown in the route that each section develops.
For the food methodology
Research into the way in which they acquire vitality is of importance and they are divided very emphatically into three general classes: saprobic, detritivorous, and ruthless or predatory living beings which are also examples of heterotrophs.
saprobic organism
They are the fundamental specialists in the disintegration and distribution of all natural matter on earth, they are the ones who assimilate supplements into dead life forms, either through fecal matter or any of its parts. The models would be most fungi and microscopic organisms, insects, worms and so on.
detritivorous creatures
They are those that retain supplements from dead creatures, either by fecal matter or any of its parts, varying from the saprobes that consolidate the supplements by sucking, biting or cutting the nutritive material. Models would be creepy crawlies, nocturnal reptiles, baby flies, sea cucumbers.
predatory life forms
It settles for animals that feed on a whole life form or parts. They are sustained by a prey, example, sharks, lions, hawks. In addition, they have various divisions according to the food that can be:
According to the method of sustaining
- Hunters: They are the individuals that catch and kill their prey, as in the case of hawks, panthers, lions and the terrible sharks.
- Scavengers: These are individuals who eat living beings that died normally or were executed by others, for example, jackals, vultures, crows.
- Parasites: They are those that ingest all the supplements of their living hosts. An example of them is lice, tapeworm or worm, also examples of heterotrophs.
According to the food root
- Omnivores: They are living consumers that feed on everything, both different creatures and plants. It's simple for omnivores to figure out something to eat in light of the fact that they eat just about anything, very particular to examples of heterotrophs.
- Carnivores: They are animal life forms that eat meat, the vitality they obtain and use comes from the lipids (fats) that the herbivore has stored inside its body.
- Herbivores: They are those who to feed themselves eat plants and vegetation (counting, trees, flora) in order to acquire their sustenance. They are essential consumers in the lifestyle in the food chain.
According to physical characteristics of the food they eat
- Macrophages: They are called captors, which in one way or another swallow their prey. These types of predators can catch their prey using suction cups, tubes, limbs, pincers, and beaks. Remember that most eat large amounts of food that are larger than their own size, lizards, snakes, flying creatures.
- Microphages: It is said that they are mostly inactive throughout life, they are largely oceanic, that they do not have devices that can grind or assimilate what they eat. It benefits from small particles of matter or small creatures, for example, ocean sponges and whales, are part of the examples of heterotrophs.
- Fluidophages: Those who ingest their supplements in aqueous form are called liquid eaters, examples of which are most insects or arachnids, mosquitoes, bugs and honey bees.
By the state of the food before eating it
Here the condition of the supplement is broken down before being ingested by the living being according to whether it is alive or dead. From the attached chart, we are more likely to understand its dispersion:
They acquire food from a dead creature
- By adsorption: They are the main operators of the distribution of natural material in the soil and detriment, for example, fungi (mushrooms) and most microscopic organisms (they are mostly saprobes).
- For active admission: Their method of giving supplements is dynamic, that is, they suck, cut or chew the healthy material.
They get food from a living life form
- For active admission: They are the supposed carnivores that obtain supplements for being alive, they can be:
- Through the hunt: Those creatures that chase their prey, examples; the terrible shark, the brave tiger, the lion, hawk, shark.
- By filtration: They have a filter frame, they are called filter channels. For example the charming and attractive whales.
- By suction: They obtain the supplements by sucking methods, they are called libators or suckers. For example, bees, mosquitoes, butterflies.
- By absorption: They are the endoparasites, those that live inside a living being and feed on supplements inside their bodies. For example, the worm or roundworm.
By trophic level and habitat
It can be well remembered that the trophic levels depend on the grouping of creatures dependent on the beginning of the matter from which they are sustained in nature and the vital space where they live.
Elemental propagation is indicated by trophic levels, considering that consumers in the environment are creatures that have a autotrophic and heterotrophic nutrition or other consumer:
- That is why the essential consumers: they are herbivorous creatures that feed on an autotroph.
- Likewise, it also locates the auxiliary consumers: They are predatory creatures that feed on an essential consumer, that is, herbivorous creatures.
- And also the Degraders: Likewise, they are called chromium decomposers by bacteria, fungi and microbes and incorporate what are saprophytes and saprophages.
If they are microorganisms
Two modalities stand out that are based on the idea of vitality that is consolidated by microorganisms as examples of heterotrophs, those that use natural matter to integrate natural atoms, that is, they are ordered by the type of food, called:
photoheterotrophs
Those who use light as a source of vitality, to create ATP in order to obtain natural mixtures of different creatures as a carbon source. One model is Rhodobacter, microscopic purple non-sulfur organisms.
chemoheterotrophs
It may well be emphasized that these living entities achieve their vigor by ingesting preformed sources of natural vitality, eg, proteins, starches, and lipids that have been mixed by others. A model, the microscopic organisms Lactobacillus.
Why are they important in the ecosystem?
Because they are the ones that cause the planet to change amazingly, because they cause a biodiversity of important types of animals to exist in biological systems and in the environment.
They structure an important part within evolved life forms in the exchange of matter and vitality. They can also more easily understand the ideas of natural life forms or food chains, trophic levels and pyramids.
heterotrophic sustenance
In the environment, heterotrophic care is completed when the cell is consuming an already established natural matter (there is no change from inorganic matter to natural matter). However, it admits the transformation of food into its own cellular matter.
PREMIUM QUALITY
For the most part, there are three types of heterotrophic feeding that spread a wide range of animal groups that can be perceived in a biological system and that together structure the phases of sustenance:
holozoic sustenance
It describes each of the individuals that sustain themselves by directly capturing or ingesting different types of life in nature. It incorporates carnivores, herbivores and omnivores. For example; birds, person, lions, tigers, sharks.
Saprophyte
It is a kind of food supply that is called saprophytism, they feed on deteriorating natural matter. Most fungi, microorganisms, larval offspring.
Parasitic
Those who acquire their food to the detriment of other living beings are known as parasitism. It incorporates as models the ticks, tapeworm or worm.
sustenance process
It is a process that involves heterotrophic sustenance of a cell (presents change of food in essential vitality) which can be divided into seven phases:
- Capture; It arises when the cell attracts food crumbs by vortexing through its flagella or cilia, emanating pseudopods, which incorporate the food itself.
- Ingestion; It is when the cell carries food to the phagosome or food vacuole. Certain hair cells - paramecia, which have a kind of mouth, called a cytostome, through which they wrap food.
- Digestion: It occurs when lysosomes release their stomach chemicals into the phagosome, which will then become the digestive vacuole. From compounds, they separate food into the small particles that make it up.
- the membrane passage: Occurs when tiny molecules discharged from the assimilation zone pass through the vacuole layer and diffuse through the cytoplasm.
- Defecation or egestion: The particles that are not useful and do not serve are eliminated to the outside.
- Metabolism: It is the arrangement of responses that occur in what is known as the cytoplasm. His motivation is to acquire vitality and manufacture his own natural cell. It is isolated in two main stages:
-
- Anabolism: It is considered the stage of development in which, taking advantage of the biochemical vitality of catabolism and the small atoms of assimilation, huge natural particles are combined.
- Catabolism phase: It is the stage of spraying, where the natural emission, through the cellular breath, is oxidized within the mitochondria, acquiring biochemical vitality.
- Excretion. The discharge is the expulsion to the outside, through the cellular web, of the waste resulting from catabolism. These elements are usually carbon dioxide CO2, water H2O and aromatic salts of NH3.
- Aging: it is an anaerobic procedure to obtain vitality from natural atoms. The last electron acceptor is a natural particle (lactic acid or ethanol). Homolactic maturation: a few microorganisms convert pyruvic acid to lactic acid.
