A. Producers are the green plants which synthesise their own food using sunlight.
B. Herbivores are primary consumers which feed on producers.
C. Carnivores are secondary consumers who feed primary consumers.
D. Top carnivores are tertiary consumers who feed on other carnivores.
Maximum energy is stored in the trophic levels of producers as they synthesise their own food. They occupy the lowest trophic level and energy is transferred from them to higher subsequent trophic levels. As the energy decreases each time it is transferred to the next higher trophic level, the lowest trophic level i.e. producers, have maximum energy.
