Question

question 22 of 50
what must be true for natural selection to happen?
a. all organisms must have the same genotype.
b. there must be competition for resources.
c. the population must be below carrying capacity.
d. there cannot be any predators.

Explanation:

Natural selection occurs when there is competition for limited resources. Organisms with traits better suited to obtain resources are more likely to survive and reproduce. Option A is incorrect as organisms have genetic variation (different genotypes). Option B is wrong because genetic variation (different genotypes) is necessary for natural selection. Option D is incorrect as predators can be part of the selective pressure in natural selection.

Answer:

C. There must be competition for resources.
