Regarding the gradients of biodiversity:

I:  As we move from poles to the equator, broadly speaking, biodiversity decreases.
II:  There is an increase in species diversity from lower to higher altitudes.

1. Only I is correct
2. Only II is correct
3. Both I and II are correct
4. Both I and II are incorrect

Which of the following is not a reason that accounts for greater biodiversity of tropics?

1. availability of more solar energy
2. more niche specialization
3. more time for species diversification
4. large seasonal variations in environmental factors

Consider the two statements:

I: Species diversity seen in tropical areas is much lower than that seen in temperate areas.
II: Temperate areas, unlike tropical areas are less seasonal, more constant and promote niche specialization.

1. Both I and II are correct and II explains I.
2. Both I and II are correct but II does not explain I.
3. I is correct but II is incorrect.
4. Both I and II are incorrect.
