A heterotroph is an organism that eats various other plants or animals for energy and nutrients. The hatchet stems indigenous the Greek words hetero for “other” and also trophe because that “nourishment.”

Organisms are characterized into two large categories based upon how they obtain their energy and also nutrients: autotrophs and also heterotrophs. Autotrophs are known as producers due to the fact that they space able to make their own food from raw materials and energy. Examples incorporate plants, algae, and some species of bacteria. Heterotrophs are known as consumers because they consume producers or other consumers. Dogs, birds, fish, and also humans room all instances of heterotrophs.

Heterotrophs occupy the 2nd and 3rd levels in a food chain, a succession of organisms that administer energy and nutrients for other organisms. Every food chain is composed of three trophic levels, which describe an organism’s role in one ecosystem. Occupying the an initial trophic level space autotrophs, such as plants and algae. Herbivores—organisms the eat plants—occupy the second level. Carnivores (organisms the eat meat) and also omnivores (organisms the eat plants and meat) occupy the 3rd level. Both primary (herbivores) and an additional (carnivores and also omnivores) consumers room heterotrophs, while major producers space autotrophs.

A third kind of heterotrophic customer is a detritivore. This organisms achieve food by feeding ~ above the remains of plants and animals and fecal matter. Detritivores play an essential role in maintaining a healthy ecosystem through recycling waste. Examples of detritivores include fungi, worms, and also insects.

There are two subcategories that heterotrophs: photoheterotrophs and chemoheterotrophs. Photoheterotrophs are organisms that acquire their energy from light, however must still consume carbon from various other organisms, together they cannot utilize carbon dioxide native the air. Chemoheterotrophs, through contrast, acquire both your energy and also carbon from various other organisms.

A significant difference between autotrophs and heterotrophs is the the former are able to do their very own food through photosynthesis vice versa, the latter cannot. Photosynthesis is a process that entails making glucose (a sugar) and oxygen indigenous water and carbon dioxide using energy from sunlight. Autotrophs are able to manufacture power from the sun, but heterotrophs need to rely on various other organisms because that energy.

Another major difference in between autotrophs and also heterotrophs is the autotrophs have crucial pigment called chlorophyll, which permits them to capture the energy of sunlight during photosynthesis, conversely, heterotrophs perform not. There is no this pigment, photosynthesis might not occur.

Heterotrophs advantage from photosynthesis in a selection of ways. They rely on the procedure for oxygen, i m sorry is produced as a byproduct during photosynthesis. Moreover, photosynthesis sustains the autotrophs that heterotrophs rely on to survive. When meat-eating carnivores might not directly depend ~ above photosynthetic plants to survive, they do depend top top other pets that consume photosynthetic plants as a food source.
