Question

why is it ineffective to constantly spray the same population of pests with the same amount of pesticide? the population will become more resistant over time. their population will increase due to biomagnification. the organisms will learn to hate and attack humans. they will slowly die off from bioaccumulation.

Explanation:

When the same pesticide is used repeatedly, pests with genetic variations that confer resistance survive. These resistant individuals reproduce, passing on the resistance trait. Over time, the proportion of resistant pests in the population increases, making the pesticide less effective. Biomagnification refers to the increase in concentration of a substance in organisms at higher trophic levels, not directly related to pesticide ineffectiveness here. Organisms don't "learn to hate and attack humans" in this context. Bioaccumulation is the accumulation of a substance in an organism, but it doesn't explain the ineffectiveness of the pesticide on the pest population as resistance does.

Answer:

The population will become more resistant over time.
