Ecologists will often represent the amount of potential food available for each trophic level in an ecosystem with a(n) biomass pyramid.

Explanation:

A biomass pyramid can be defined as a diagram which quantifies the biomass as we move up the trophic levels in a pyramid. It is often plotted as the food (in calories or grams) per unit area. The biomass pyramid quantifies the biomass present at each trophic level.

Hence, a pyramid of biomass is the best way to represent the amount of food available at each trophic levels in a pyramid.
