Question

suppose that a plant disease kills all the fruit. the change could become a ______ on the birds.
options:
natural selection
selective pressure
genetic variation

Explanation:

Selective pressure refers to an environmental factor that reduces the survival or reproductive success of organisms without specific traits. The loss of fruit removes a food source for birds, creating pressure that affects their survival and reproduction, driving potential evolutionary changes. Natural selection is the process that results from such pressure, while genetic variation is the existing trait diversity that selection acts on.

Answer:

selective pressure
