Ecological Concepts

We have learned a lot of important ecological concepts this unit. Briefly explain TWO of the following ecological concepts and provide an example for each you described. I expect more than just a sentence for each; demonstrate depth, breadth and application in your responses.

1. Ecological succession – include what it is and the difference between primary and secondary
2. One-way flow of energy between trophic levels – what does this mean and address why energy is not cycled like nutrients
3. Limiting factors – what are they and provide two specific examples
4. Carrying capacity – what is it and how it may be affected over time
