Question

What might happen to an ecological pyramid of numbers in a forest ecosystem if most of the deer were killed due to hunting by people and disease?

Answer 1

The predator numbers for the deer will start to drop, due to a lack of food available. The vegetation that deer eat will increase, due to a lack of deer to eat it & so it will thrive untamed. This may cause certain animals to thrive & increase their respective predator counts & so on.
