Ecology Review
Interactions Among Living Things
#20
Name _________________________
We are going to take about 5 class periods to review the ecology concepts you learned in 6th grade.
There are 4 ecology standards that will be part of this review:
13. Give examples of ways in which organisms interact and have different functions within an
ecosystem that enable the ecosystem to survive.
14. Explain the roles and relationships among producers, consumers, and decomposers in the process of
energy transfer in a food web.
15. Explain how dead plants and animals are broken down by other living organisms and how this
process contributes to the system as a whole.
17. Identify ways in which ecosystems have changed throughout geologic time in response to physical
conditions, interactions among organisms, and the actions of humans. Describe how changes may be
catastrophes such as volcanic eruptions or ice storms.
