SOLUTION :In a forest ECOSYSTEM the PYRAMID of number is spindle in shape, it is because the base `(T_1)` of the pyramid occupies large sized trees (Producer) which are lesser in number. Herbivores `(T_2`) (Fruit eating birds, elephant and deer) occupying second trophic LEVEL, are more in number than the producers. In FINAL trophic level `(T_4)`, tertiary consumers (lion) are lesser in number than the secondary consumer `(T_3)` (fox and snake).
