(d) All the given

Answer 1

(b) increases or
(c) increases and decreases

Answer 2

As we move from the polar region towards the equator, the biodiversity gradually increases.

Option: (b)

Explanation:

• The spread of the Biodiversity depends on the variation of climatic conditions across the globe.

• The atmospheric conditions on and near the polar regions are such that the temperatures are extremely low because of the presence of ice beds and glaciers.

• As we gradually move towards the equator, the temperature increases and happens to be optimum for the survival of different species of organisms.

• Thus, the biodiversity increases as we move away from polar regions to the equatorial region.
