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.

these macromolecules could either be amino acids, proteins or nucleic acids. they are responsible for the chemical changes and reactions that affects largely the cell and its composition. take for instance the cytoplasm of the cell where these organelles are settled. these simple organelles are composed of macromolecules which ignites and catalyses different functions that enables cells, in macro-perspective in motion and metabolism. in intestines for example, metabolism happens and breaking down parts of a food to simpler compounds that are used and these nutrients delivered throughout the body and again broken down by into smaller components.
