4. Describe mutualism and give three examples.
5. Describe Communalism and give three examples.
6. Describe predator-mediated competition and give an example.
7. List some reasons why a keystone species is important to a community.
Most Important: (Your own words – Write at least one complete sentence summarizing what you think is the most important part of this module that you
should carry with you and why it is important. If there is more than one, then write them all!)
