Question

The use of a pesticide may result in an increase in the number of pest organisms that are resistant to the pesticide. Use your knowledge of natural selection to explain the increase in the number of pest organisms that are resistant to the pesticide. (5)​

Answer 1

answer given in explanation

Explanation:

• Natural selection is a process by which the forms organism best adapted to an environment that increase their number of offspring and chance of survival than less adapted organism.
• In an area where use of pesticide is higher, pest of these area try to modify their gene in order to ensure their survival.
• The pests which are unable to acquire resistance will not be able to survive in harsh condition( area where pesticide is used). so nature does not select this weak pesticide sensitive  pest, so they ultimately will be eliminated
• on the other hand those pest that acquire resistance against pesticide able to survive better in harsh condition so they are selected by nature, produce large number of resistant offspring. in this way use of pesticide increase the number of pesticide resistant pest.
