  1. Environments and Life

  2. Changes in Ecosystems • Life changes environments • Older inhabitants die and are replaced by new plants and animals • Plants change soil, allowing new plants to move in • Plant communities change trees can appear • Read about Rakata Island on page 106

  3. Ecological Succession • The process by which an existing ecosystem is gradually and progressively replaced by another ecosystem • Good Illustration: Look at figure 4-12 and 4-13 on page 106 and 107.

  4. Climax Community • The relatively stable collection of plants and animals that result when a relatively stable state is reached in the interaction between organisms and their environment • Climax communities do change • Fires, floods, wind, humans. • Succession begins again
