Question

Autotrophic organisms are able to take inorganic molecules and transform them into organic nourishment by using light or chemical energy. Why are autotrophic organisms considered essential to all other life on earth?

They use high levels of oxygen in their chemical reactions.

They exist in smaller numbers as compared to heterotrophs.

They increase the atmospheric levels of carbon dioxide.

They are the primary producers at the base of the food chain.

Answer 1

@laurisve Well, I have to go, but I leave with this: all heterotrophs must use organic nourishments (should be nutrients) to survive, but cannot make their own. So, why then would autotrophs, which make these organic nutrients, be essential to all life?
