Athena Howe · Answer 1

D. natural selection

Explanation:

Natural selection is an evolutionary process in which organisms that are better adapted to changes in the environment survive and contribute more to the subsequent generations in terms of reproduction.

The weak organisms gradually phase out of the population because they are weakly adapted to changes in the environment. Hence, they are not able to survive and or reproduce.

Hence, processes whereby some animals are better able to survive and reproduce under changing environmental conditions ahead of others are natural selection processes.
