Pyramid of energy: It shows the rate of energy flow and productivity at succesive tropic levels.It is always upright.

-Pyramid of number in forest ecosystem:

In a forest ecosystem, the producers are large size trees which make the base of pyramid.The herbivores such as fruit eating birds,deer,elephants etc.make the primary consumers and are less than primary producers.After that,the number goes down at each succcessive level.Thus, a pyramid o number in a forest ecosystem is partially upright or spindle shaped.
