Isn't it pretty clear what plants do?
Living one day at a time;
Enjoying one moment at a time;
Accepting hardships as the pathway to peace;

:lol: laf

plants and protists are primary consumers of both minerals and sunlight. Protists and bacteria do most of the mineral fixing (though protists do a LOT of photosynthesis too - phytoplankton). Plants use minerals fixed by protists and bacteria, so I guess you could say protists and bacteria are the primary consumers, BUT, protists and bacteria also eat other one-celled organisms, or feed off of larger dead organisms, SO, the line is kinda shady.

Animals and bugs eat plants and protists/bacteria/fungi. They make up the rest of the food "chain" except that in the end, the bacteria/protists/fungi get a nice meal off of their dead bodies. Not to mention the symbiotic or parasitic bacteria/fungi/protists that feed off of living animals. So I guess in some ways the little guys are on the top of the food chain... and the bottom...

Have I sufficiently confused you? Good.
