Climatic limitations of the area
<h3><u>Explanation;</u></h3>
- Climatic climax is a stage in which the plant species live in perfect balance with the current environmental conditions. Although climate is the major influence on vegetation at a global scale, on a local scale other factors such as drainage, geology and relief affect plant growth.
- In the process of ecological succession, one community replaces another until a climax community is established. The type of climatic vegetation that grows in a certain geographical area is most directly influenced by a climatic limitations of an area.
- <em><u>A climax community is able to exist in a certain geographic region for a long period of time because it remains in equilibrium with the environment.</u></em>
- <em><u>Ecosystems tend to change with time until a stable system is formed. All stable ecosystems are characterized by the presence of a specific climax vegetation influenced by the climate of the area</u></em>.
