I: | In general, species diversity decreases as we move away from the equator towards the poles. |
II: | With very few exceptions, tropics harbour more species than temperate or polar areas. |
Assertion (A): | Tropics have greater biodiversity than other regions on Earth. |
Reason (R): | Tropics are subjected to larger seasonal variations than other regions on Earth. |
1. | Both (A) and (R) are True and (R) correctly explains (A). |
2. | (A) is True but (R) is False |
3. | (A) is False but (R) is True |
4. | Both (A) and (R) are True but (R) does not correctly explain (A). |
Statement I: | Tropics have greater biodiversity than other areas on Earth. |
Statement II: | Tropics are farthest from the equator on the Earth. |
Assertion (A): | Tropics have provided more evolutionary time for species diversification |
Reason (R): | The species diversity in tropics is lower than in the temperate regions. |
