please pick two to answer 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 timeExplanation / Answer
1.Ecological succession is the gradual replacement of one type of ecological community by another in the same area involving a series of orderly change.
Primary ecological succession is seen in new area that is previously not support by the ecological community such as barren land,newly exposed rocks formed the lava flow
Where as secondary ecological succession occurs in an area disturbed or destroyed by natural disasters such as fires and floods or sometime by the human activity of clear cutting ,and there new community moves in that area.
4.carrying capacity is basically a limit of the size of the population that can live indefinitely using the resources available at that place without depleting or degrading the resources.
Carrying capacity of an environment may change over time due to the factors including availability of food and supply of water,living space and environmental condition.
It is best described the example as there is a food only for 5 people ,if the number of people raised to 10 then they will starve and when number get reduced it is best utilized among them.
