My Ecosystem
You are going to create an imaginary ecosystem. You can show me this ecosystem by making a poster, a
book, video or a story. In your ecosystem you must explain the following concepts
-
-
-
-
Symbiosis
o Mutualism
o Commensalism
o competition
o Parasitism, and
o Predation
Succession
o Primary, and
o Secondary
Introduction of a new species
Energy flow through systems
o A food web
o A food chain, and
o A pyramid
Abiotic characteristics
You will be marked on the following rubric:
Score 4
