Question

The shape of pyramid in a particular ecosystem is always different in shape. Explain with example.

Answer 1

In a forest ecosystem, the pyramid of number is spindle in shape, it is because the base (T₁) of the pyramid occupies large-sized trees (Producer) which are lesser in number. Herbivores (T₂) (Fruit-eating birds, elephants, and deer) occupying the second trophic level, are more in number than the producers. In the final trophic level (T₄), .tertiary consumers (lion) are lesser in number than the secondary consumer (T₃) (fox and snake).
