Explanation:
Pesticides are used to kill or stop the growth of insects that are harmful for crops but use of pesticides reduces biodiversity by killing a wide variety of insects.
Insects are one of the important component participate in the process of pollination that increases the biodiversity. insects move from one flower to other flower and spread pollen for reproduction.
