primarily photoautotrophs, like plants and algae, that use the energy of light to convert carbon dioxide to organic matter.

and to a small extent, chemoautotrophs — bacteria and archaeans that do the same but use the energy derived from an oxidation of molecules in their substrate.

Omnivores eat plants, but not all kinds of plants.

Omnivores can't digest some of the substances in grains or other plants that do not produce fruit.

They can eat fruits and vegetables, though. Some of the insect omnivores in this simulation are pollinators, which are very important to the life cycle of some kinds of plants.
