Most autotrophs make their "food" through photosynthesis using the energy of the sun. Heterotrophs cannot make their own food, so they must eat or absorb it. Chemosynthesis is used to produce food using the chemical energy stored in inorganic molecules.
In respect to this, what is an autotrophic organism?
autotroph. [ô′t?-trŏf′] An organism that manufactures its own food from inorganic substances, such as carbon dioxide and ammonia. Most autotrophs, such as green plants, certain algae, and photosynthetic bacteria, use light for energy.
Are all bacteria heterotrophic Why?
Bacteria. Bacteria: Any of a group of microscopic organisms that are prokaryotic, i.e., that lack a membrane-bound nucleus or organelles. Chemotrophs are usually heterotrophic, but some species of bacteria exist than can acquire energy from inorganic chemicals.
Are fungi heterotrophic or autotrophic?
Most opisthokonts and prokaryotes are heterotrophic; in particular, all animals and fungi are heterotrophs. Some animals, such as corals, form symbiotic relationships with autotrophs and obtain organic carbon in this way.
