- 1.From amongst these, what is an example of bottom-up population regulation?
- A.
A drought causes grasses to decline, which reduces the number of grasshoppers. In turn, this reduces the number of shrews
- B.
In a freshwater stream, bass prey on snail darters. The darters hide in rocky shelters, where crayfish prey on them. As a result, the darter population declines.
- C.
Bald eagle populations decline as a result of bioaccumulation of DDT in their bodies. As a result, the rat population of the region increases.
