Question

a farmer sprays an insecticide on his tomato plants to kill the insects that are eating the leaves. some of the insects are resistant to the pesticide.
what process is demonstrated by this example?
abiogenesis
bioaccumulation
biogenesis
natural selection

Explanation:

Natural selection is the process where organisms better adapted to their environment survive and reproduce more successfully. In this case, the pesticide acts as a selective pressure. Insects resistant to the pesticide (black ones) survive after pesticide application. In the later generation, there are more resistant insects (black ones) because they passed on their resistance - related traits. Abiogenesis is the origin of life from non - life. Bioaccumulation is the accumulation of substances in an organism. Biogenesis is the production of life from life. None of these other concepts fit the described scenario of differential survival and reproduction based on a trait (pesticide resistance).

Answer:

natural selection
