Question

1. identify which trophic level, if removed from a food web, would likely cause the most change in the ecosystem? a. producer b. primary consumer c. secondary consumer d. tertiary consumer

Explanation:

Producers are the base of the food - web, converting energy from the sun into chemical energy through photosynthesis. All other trophic levels depend on producers for energy. Removal of producers would lead to a collapse of the entire food - web as primary consumers would have no food source, which would then affect secondary and tertiary consumers.

Answer:

A. producer
