Mangrove trees have many special adaptations for life in saltwater along coasts, they are the keystone species in mangrove swamps. Due to constant warm temperatures and large amounts of rainfall the leaves of a mangrove do not fall off all at once at a certain time of year. They are evergreen. The leaves have drip tips which allow rainwater to drain off quickly. Scientists believe this helps to prevent the growth of harmful bacteria on the trees. Evaluating the physical factors of the environment and the mangrove's adaptations suggests that they are most likely found in

• tropical or subtropical zones

• temperate or subtropical zones

• northern or southern areas

• tropical or northern areas

Which of the following statements is not correct?

• Grasslands have rich soil that supports abundant plant life.

• The tundra is a fragile biome because conditions are severe, and the ecosystem is easily disrupted.

• Chaparral fires are beneficial because they destroy trees that compete for light and space.

• Tropical rain forests are resistant to change because the plants contain so many nutrients.
