Detailed explanation-1: -Base of ecological pyramids are producers which are the energy factories of ecosystem and repositories of all energy in an 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: -Producers are at the bottom of the pyramid because they are able to transform the sun’s energy into a large amount of plant energy through the process of photosynthesis. Producers are the base of energy for most food chains and food webs. Animals that eat plants make up the next level.

Detailed explanation-4: -The basis of an ecological pyramid is the biomass, energy, and number. Just as the name suggests ecological pyramids are in the shape of a pyramid. The bottom of an ecological pyramid is the broadest and is occupied the producers, which form the first trophic level. Producers are at the lowest level.

Detailed explanation-5: -The bottom and largest level of the pyramid is the producers and contains the largest amount of energy. As you move up the pyramid, through the trophic levels to primary, secondary and tertiary consumers, the amount of energy decreases and the levels become smaller.
