Detailed explanation-1: -Producers such as algae and plants are the organisms that would most likely be found at the bottom of biomass pyramid because producers are the organisms that make their own food from using the sun energy and feed other organisms present in that ecosystem.

Detailed explanation-2: -The base of the pyramid is composed of species called autotrophs, the primary producers of the ecosystem. All other organisms in the ecosystem are consumers called heterotrophs, which either directly or indirectly depend on the primary producers for food energy.

Detailed explanation-3: -The primary producers will lie at the bottom of the biomass pyramid. In this case, grasses, trees, flowers, and shrubs make up the needed fuel for the primary consumers that are up on the food chain. The primary consumers are herbivores: squirrels, deer, insects, and birds that feed on trees and grasses.

Detailed explanation-4: -Producers, who make their own food using photosynthesis or chemosynthesis, make up the bottom of the trophic pyramid. Primary consumers, mostly herbivores, exist at the next level, and secondary and tertiary consumers, omnivores and carnivores, follow.

Detailed explanation-5: -At the lowest trophic level, the primary producers, there is the least amount of biomass and as the trophic levels increase the biomass increases.
