How does the shape of the earth and its tilted axis influence where terrestrial communities are found?

The Earth has got its tilted axis and this is the reason for different seasons to be formed. Communities are a set of population found in that particular area and are of two types.  

A) Terrestrial (Land)

B) Aquatic (Water).

These communities to flourish need a perfect environment with a perfect season.  Hence according to the season formed due to the tilted axis influences the  terrestrial community which forms in that particular region and have the ability for the region specific community growth.

The terrestrial community of a tundra or desert or rain forest all depends on the particular season that can be formed due to the position of the earth facing the sun.
