Correct answer: D. Tropical evergreen forests
- A. Temperate forests
- B. Oceanic island communities
- C. Mangroves
- D. Tropical evergreen forests
Explanation
Tropical forests are found in the tropical zone of the world and are characterized by very high temperatures with rainfall in abundance. The flora of a tropical rainforest is very rich and highly diversified. The tropical forests have a very rich fauna both in density as well as in varieties. The reason for this high diversity and variety of flora and fauna is the occurrence of suitable conditions in these forests. So these are more vulnerable to invasion by outside plants and animals.
