Question

A pond has several varieties of a species of frog that all eat the

same kind of bug. Most of the frogs are fast-growing varieties that need to eat more bugs each day than the slow-growing variety. A drought drastically reduces the number of bugs, and the population of the fast-growing frogs declines drastically while the population of slow-growing frogs declines only slightly. Most of the frogs in the pond are now the slow-growing variety. This is an example of which of the following?
A) evolution
B) mutations
C) acquired characteristics
D) natural selection
E) artificial selection

Answer 1

Answer 2

Natural selection

Step-by-step explanation:

Natural selection is a process of evolution where organisms becomes better adapted to their environment through the different reproductive success of the individuals.

Since the slow growing frogs required fewer bugs, they were better able to survive. Since they were better able to survive, they produced more offspring that were also slow growing. In this way, the environment selected for the trait that improved the organisms survival.
