Using an example for each, explain the following ecological concepts. a) Succession

b) Energy flow between trophic levels

c) Limiting factors

1-Ecological succession is the process of change in the species structure of an ecological community over time.

2-Energy decreases as it moves up trophic levels because energy is lost as metabolic heat when the organisms from one trophic level are consumed by organisms from the next level.

3-A limiting factor is a variable of a system that causes a noticeable change in output or another measure of a type of system.
