Explanation

In a terrestrial ecosystem, the trophic level that would contain the largest biomass would be the producers. A biomass pyramid shows the amount of biomass at each trophic level. Terrestrial biomass generally decreases markedly at each higher trophic level. Examples of terrestrial producers are grasses, trees and shrubs. These have a much higher biomass than the animals that consume them such as deer, zebras and insects. The levels with the least biomass are the highest predators in the food chain such as foxes and eagles, etc.
