Question

# In general, latitudinal gradient states that species diversity  as we move away from the equator towards the poles.

A
increases
B
decreases
C
same
D
can be predicted

Solution

## The correct option is B decreasesIn general, latitudinal gradient states that species diversity decreases as we move away from the equator towards the poles. So, the tropical regions are more diverse in species than the polar regions. Ecologists have porposed various hypotheses for this: i) tropical latitudes have remained relatively undisturbed ii) tropical environments are relatively more constant and predictable iii) more solar energy is available in the tropics.
