Detailed explanation-1: -All the animals or consumers depend on plants for their survival or food. So, we say that the base of an ecological pyramid represents the producers or first trophic levels i.e. plants.

Detailed explanation-2: -Description. An energy pyramid, also known as a trophic or ecological pyramid, is a graphical representation of the energy found within the trophic levels of an ecosystem. The bottom and largest level of the pyramid is the producers and contains the largest amount of energy.

Detailed explanation-3: -Ecological pyramids begin with producers on the bottom (such as plants) and proceed through the various trophic levels (such as herbivores that eat plants, then carnivores that eat flesh, then omnivores that eat both plants and flesh, and so on). The highest level is the top of the food chain.
