Question

Which of the following best explains why a finite supply of environmental resources is important to differential reproductive success?
A
Limited resources create selection pressures for survival on the population.
B
Variations within a population allow for differential reproductive success.
C
Some members of a population survive competition but never reproduce.
D
Natural selection does not occur when the environment limits the supply of resources.

Answer 1

A

Limited resources create competition and thus selection pressures; individuals with advantageous traits are more likely to survive and reproduce, producing differential reproductive success.
