Detailed explanation-1: -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.

Detailed explanation-2: -The green plants in the ecosystem are called producers and they make the first trophic level of the food chain having the greatest amount of energy.

Detailed explanation-3: -The majority of the energy is used by the organism or released to the environment. The energy pyramid shows four levels of a food chain, from producers to carnivores.

Detailed explanation-4: -At the bottom of the pyramid, you have producers. These are usually plants or other photosynthetic organisms, such as algae or photosynthetic bacteria. Producers are autotrophs, meaning they are self-feeding organisms that do so by making their own organic molecules.

Detailed explanation-5: -According to the pyramid of energy, the energy content is maximum in autotrophs or producers. Autotrophs are the plants which prepare their food by photosynthesis. They are the primary producers and primary source of food energy. The flow of energy is unidirectional from producer to consumer level.
