Question

which best describes the process that the pest population has experienced due to this environmental change? genetic diversity natural selection natural resistance gene flow

Explanation:

The image shows that only red pests survived an environmental change, and they reproduced to form a new population of red pests. This matches natural selection, where organisms with traits suited to the environment survive and pass on those traits, while unsuited ones (green pests here) are eliminated. Genetic diversity refers to variation in a population, natural resistance is a trait, and gene flow is transfer of genes between populations, none of which fit this scenario.

Answer:

natural selection
