Explanation:
Detailed explanation-1: -The base of the pyramid is composed of species called autotrophs, the primary producers of the ecosystem.
Detailed explanation-2: -At the base of the pyramid are the producers, who use photosynthesis or chemosynthesis to make their own food. Herbivores or primary consumers, make up the second level. Secondary and tertiary consumers, omnivores and carnivores, follow in the subsequent sections of the pyramid.
