Answer:
D. lower yields of fruit crops, due to decreased pollination
Step-by-step 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. Due to pesticides some of the insects important for pollination got killed and reduces the pollination process. If pollination process will decrease, it will impact lower rate of reproduction of fruit crop.
Hence, the correct option is "D. lower yields of fruit crops, due to decreased pollination".
