All life organisms in the people can be classified as either one autotroph or heterotroph. An autotroph is an organism that deserve to make its own food for energy. A heterotroph is not capable of do its own food. They rely on other organisms to administer them with the energy needed to survive.

Organisms that are classified together being decomposers, consumers, and also detritivores room all categorized together being heterotrophs. These teams consist of all animals, fungi species, and also some varieties of bacteria the exist throughout the world. Heterotrophs consist of the 2nd and third levels of the food chain.

Decomposers are organisms found at the end of the food chain. They space responsible for returning the nutrients offered from dead organisms earlier into the soil, i m sorry is provided by autotrophs for their photosynthesis cycles. These nutrients consist that phosphorus, nitrogen, and also carbon. Most decomposers consists bacteria.

The process of decomposition takes location while the organisms space in their not natural state. This process is much more commonly described as nitrogen fixation. During this process, the biology transforms gaseous nitrogen discovered in the setting into elements, consisting of ammonia, nitrate, and nitrite. These facets are supplied by various other living things at various levels of the food chain to produce energy for sustaining their very own life cycle.

Here room some examples of decomposers:



Consumers deserve to be broken up right into herbivores, carnivores, or omnivores. Herbivores rely on plants to provide them v the energy and also nutrients crucial for living. Part examples encompass rabbits, squirrels, mice, and also giraffes.

Carnivores space organisms that call for meat to attain energy. Often, carnivores feed on herbivores. An example of this is a cat that eats a computer mouse for food. Other instances of carnivores include:


Omnivores room consumers that depend on both plants and also meat come sustain life. Humans fall within this category on the food chain. This is because of their ability to acquire energy from foods, such as fruits and also vegetables, when requiring various other nutrients such together iron and protein provided by animals. Some other examples of omnivores include:



Detritivores count on organic waste created by various other living organisms to sustain their life. This issue can encompass the decomposed issue from dead trees, plants, or animals. This type of heterotroph contains living organisms together as:


Two forms of Heterotrophs

To know heterotrophs further, researchers have broken herbivores, carnivores, and omnivores up into two separate classifications. These include chemoheterotrophs and also photoheterotrophs.

A chemoheterotroph calls for energy and carbon the is listed by other living organisms. Phototrophs usage light indigenous the sun to offer them energy but must tho consume other living biology to provide them with carbon.
