Question
Chapter 53.2, Problem 2SB
Summary Introduction
To review:
The reason behind finding more species living in an ecotone, than in the communities on either side if it.
Introduction:
The interaction between populations affects the formation of ecological communities. Many hypotheses are developed to predict the nature of ecological communities. Frederic Clément’s an interactive view of communities and Gleason’s individualistic view on ecological communities.

If you had to monitor an ecosystem for evidence of pollution, what are one or two indicator species you would want to pay particularly close attention to? You may discuss specific species of organisms, or can discuss organisms that occupy a specific trophic level in an ecosystem’s food web. Explain why you would select these species or this trophic level.
If a community within an ecosystem is stable does that mean the entire ecosystem can be considered stable as well?
