A heterotroph is an organism the eats other plants or animals for energy and nutrients. The term stems indigenous the Greek words hetero for “other” and trophe for “nourishment.”
Organisms are defined into two vast categories based upon exactly how they acquire their energy and also nutrients: autotrophs and heterotrophs. Autotrophs are known as producers because they room able to do their own food from raw materials and also energy. Examples incorporate plants, algae, and some varieties of bacteria. Heterotrophs are well-known as consumers because they consume producer or various other consumers. Dogs, birds, fish, and also humans space all examples of heterotrophs.
Heterotrophs occupy the 2nd and 3rd levels in a food chain, a sequence of organisms that provide energy and also nutrients for various other organisms. Each food chain is composed of 3 trophic levels, which explain an organism’s role in an ecosystem. Occupying the first trophic level space autotrophs, such as plants and also algae. Herbivores—organisms that eat plants—occupy the second level. Carnivores (organisms the eat meat) and omnivores (organisms the eat plants and also meat) accounting the 3rd level. Both major (herbivores) and an additional (carnivores and also omnivores) consumers room heterotrophs, while main producers space autotrophs.
A third form of heterotrophic customer is a detritivore. This organisms achieve food through feeding top top the stays of plants and animals and fecal matter. Detritivores play an essential role in preserving a healthy ecosystem by recycling waste. Examples of detritivores include fungi, worms, and insects.
There space two subcategories of heterotrophs: photoheterotrophs and also chemoheterotrophs. Photoheterotrophs are organisms that get their energy from light, but must quiet consume carbon from various other organisms, as they cannot make use of carbon dioxide from the air. Chemoheterotrophs, through contrast, get both their energy and carbon from various other organisms.
A major difference between autotrophs and heterotrophs is that the previous are may be to do their very own food by photosynthesis whereas the last cannot. Photosynthesis is a procedure that involves making glucose (a sugar) and also oxygen from water and also carbon dioxide using energy from sunlight. Autotrophs are able come manufacture energy from the sun, yet heterotrophs need to rely on various other organisms for energy.
Another significant difference between autotrophs and heterotrophs is the autotrophs have critical pigment called chlorophyll, which permits them to capture the power of sunlight throughout photosynthesis, whereas heterotrophs execute not. Without this pigment, photosynthesis might not occur.

Heterotrophs advantage from photosynthesis in a variety of ways. They count on the procedure for oxygen, i m sorry is created as a byproduct throughout photosynthesis. Moreover, photosynthesis sustains the autotrophs that heterotrophs depend on to survive. While meat-eating carnivores might not straight depend top top photosynthetic plants to survive, they execute depend on other animals that consume photosynthetic plants as a food source.
