WebWhen we're talking about their role in food chains, we can call autotrophs producers. Heterotrophs, also known as other-feeders, can't capture light or chemical energy to make their own food out of carbon dioxide. Humans are heterotrophs. Instead, heterotrophs get organic molecules by eating other organisms or their byproducts. WebApr 9, 2024 · The carbon cycle on the land is called the terrestrial biosphere, all it includes all the living creatures living on the surface of the planet earth. Around 500 gigatons of carbon are stored in this biosphere above ground in the form of plants and other living organisms.
