Pyramid of number represents the number of species in each trophic level.

• Primary consumers are those organisms that depend on the producers for the source of their food. They are also known as herbivores.
• Secondary consumers are those organisms that eat primary consumers for energy. They can be either carnivores or omnivores.
• In a pyramid of number, representing an ecosystem of a large fresh water pond, the number of primary consumers (zooplankton) is more than the secondary consumers (fish).
• Furthermore, energy at the lower trophic level is always higher than that of the higher trophic level.
