Pyramids

Question 2

what do we use to represent the number in each level to make a pyramid shape.

Answer 2

We use boxes to represent the number in each level to make a pyramid shape.

why does the number of organisms get smaller

Answer 3

This is because not all energy that is being passed along the food chain makes it to the next level. Some of it is used in living and some is trapped in the undigested parts when eaten.

Chains with large producers or small consumers might not make a pyramid shape
