7.1.1. A small area or region with a relatively hot temperature in comparison to its surroundings.
7.2. Ecological Succession
7.2.1. The gradual process of change in an ecosystem brought about by the progressive replacement of one community by another in a definite order.
7.3. Primary Succession- Is one of two types of biological and ecological succession of plant life, occurring in an environment in which new substrate devoid of vegetation and usually lacking soil, such as a lava flow or area left from retreated glacier.
7.4. Secondary Succession
7.4.1. As opposed to primary successio, secondary succession is a process started by an event that reduces an already established ecosystem.
