Could there be a food chain without herbivores and carnivores? explain your reasoning.

No.

Explanation:

No, the food chain needs each other to provide food for each other. If say deer were removed from the food chain then wolfs and coyotes could not feed off of them which means they could die which means bears lose food and they could possibly die etc.

There are a few different organisms in the food chain. The producers, usually plants, we have already talked about, and then there are the herbivores and carnivores. There are also decomposers, which break down dead organisms. Decomposers can be fungi or bacteria. They grow on both plants and animals, recycling their bodies back to the soil for new growth.
