Explain Producer and Consumer Roles Practice Test

Producers are the main organisms that convert organic carbon into CO$_2$, which is why they are at the top of food chains.

Producers are not important to carbon movement because consumers can make sugars directly from CO$_2$.

Producers obtain carbon by eating decomposers, which turns inorganic carbon into organic carbon.

Producers fix inorganic carbon (CO$_2$) into organic molecules, forming the base of food chains that supply carbon to consumers.
