keep populations balanced
Layer A is above Layer B. Layer C is at the bottom. There is an intrusion (Labeled "D") that cuts through Layer C and B. Which layer is the youngest.
Explain what will happen if the number of Apex Predators is equal to or greater than the number of primary consumers.
The predators will over-consume leading the loss of population in the primary consumers. This will eventually lead to no food for the predators and the ecosystem will lose balance.
