Nothing Succeeds Like Succession
... Succession is the orderly replacement of plant and animal species through time in a given location. A. This will lead to a stable ecosystem. B. You see this when you watch a vacant lot that no one messes with. You start with grass and eventually you get bushes and trees. C. In places like Hawaii whe ...
