What would happen if we remove a producer from a food web?

The Consumer who ate the Producer would die out.

Explanation:

Every living organism will die.

Explanation:

Plants are the only organisms that can make their own food. The removal of producers would cause the entire food web to collapse. Primary consumers (herbivores), which feast on producers directly, would die off. Including us humans, since we get our food from the earth's soil, in other words, from plants. Secondary consumers (carnivores) are the next to be affected: they are the ones that eat primary consumers. Superior consumers would suffer as organisms of lower trophic levels begin to die off. Decomposers would break down corpses of dead animals, returning their fundamental components and composites to the environment. Nevertheless, even these dead organisms would run out, and the entire food web would collapse.
