Question

Many chemical pesticides can be found in the bark and leaves of tropical plants. What is a difference in tropical plants that makes it especially beneficial to produce compounds that kill insects throughout the year?

a. Because plants have to protect themselves year-round, as cold spells in winter do not kill pests as they do in temperate areas.
b. Because the plants must protect themselves from insects as repellants and toxins sprayed by humans do not work in tropical areas.
c. Because the compounds produced to kill insects also enhances the ability of the plant to recover from damage caused by various phenomena.
d. Because compounds produced to kill insects also influence the behavior and growth of tropical plants.

Answer 1

Tropical plants produce compounds that kill insects throughout the year to protect themselves from pests that are not killed off by cold spells. These compounds also enhance the plants' ability to recover from damage and protect them from insects as repellants and toxins sprayed by humans do not work well in tropical areas.

Step-by-step explanation:

Tropical plants produce compounds that kill insects throughout the year because the plants need to protect themselves year-round. In tropical areas, pests are not killed off by cold spells in winter, unlike in temperate areas. Therefore, tropical plants have developed the ability to produce chemical pesticides in their bark and leaves as a defense mechanism.

These compounds produced to kill insects also influence the behavior and growth of tropical plants. They not only protect the plants from insects but also enhance their ability to recover from damage caused by various phenomena.

In addition, tropical plants must protect themselves from insects as repellants and toxins sprayed by humans do not work well in tropical areas. Therefore, producing compounds that kill insects throughout the year is especially beneficial for tropical plants.
