Question

1. The habitat complexity hypothesis may partially explain why the tropics have particularly high diversity. The habitat complexity hypothesis suggests that tropical biodiversity is high in part because:
   1. The tropics have longer seasons than temperate zones
   2. Tropical climates are more variable than temperate climates
   3. Dense vegetation in the tropics creates a structurally complex habitat
   4. Tropics have many more soil types than temperate zones

Answer 1

The answer is ------- c. Dense vegetation in tropics creates a structurally complex habitat.

Explanation :

Tropics have warm climate which is stable when compared to temperate climate which provides the varied vegetation and also the soil is rich and fertile due to this vegetation. The leaves from trees which live around 200 to 500 years fall down which later gets decomposed making the soil fertile. Thus the answer is dense vegetation in tropics creates a structurally complex vegetation as per habitat complexity hypothesis.

While the other options include-

• Tropics have more stable climate compared with temperate zones.
