Junipers grow in tropical zone.

Methanogens, growing anaerobically on cellulosic material produce

Biodiversity is rich in tropics because of

Which of the following is a reason for the greater biological diversity of tropical regions ? (a) Tropical latitudes have remained almost undisturbed for millions of years. (b) Tropical environments are less seasonal, relatively more constant and predictable. (c) More solar energy is available in the tropics, resulting in high productivity. (d) All of these

Plants growing on rocks and stones.

In the tropical rainforest, the majority of trees have showy animal-pollinated flowers. In temperate forests the majority of trees are wind pollinated. Which factors best explain these contrasting patterns ? (i) Wind is rare in tropical forests. (ii) Because of high species diversity in the tropics, individuals of trees species are often widely separated making wind an inefficient means of pollen dispersal. (iii) More opportunities for coevolved mutualisms exist in tropical forests because of the high diversity of animal species. (iv) Trees in tropical forests are mostly evergreen and year-round leaf canopies impede pollen dispersal by wind. (v) Flowering in tropical forests occurs over a short period of time when wind is absent. (a) (i) , (ii) and (v) (b) (i),(iii) and (v) (c) (ii), (iii) and (iv) (d) (ii) and (iv)
