Ecosystems (2/16-2/19):
- You will need to know the difference between biotic and abiotic factors.
- Define population, community, and ecosystem.
- Project #1 for this nine weeks: Build and bring in a 3-D model of an ecosystem energy pyramid. It needs to have labeled examples of producers, consumers, and decomposers arranged in their appropraite trophic levels. It also needs to show and describe the flow of energy through the pyramid.
Rubric:
- Total points- points
10 points- Project is in 3-D
10 points- Project focuses on only one ecosystem (choices include forest, desert, freshwater, open ocean, jungle/rain forest, estuary/Everglades, savannah)
30 points- Project includes and labels the following:
- at least 3 producers/autotrophs
- 4-5 examples of herbivores
- 2-3 tertiary or secondary carnivores
- 1 apex/top predator
- 2 examples of decomposers
20 points- Project shows how energy flows through the ecosystem and explains whether energy increases or decreases at each trophic level
10 points- Project explains how abiotic and biotic factors in that particular ecosystem interact and affect one another.
Total: 80 points (10 point bonus if you do a coral reef, late Jurassic, late Cretaceous, or Ice Age ecosystem)
The due date is set for March 15-19. No extensions or revisions will be made. Consideration will be given for unavoidable absences but you have the better part of 3 weeks to complete this assignment. This is an individual assignment, no teams. I want to see what each person can do with the information we are learning. Helpful references and sites will be forthcoming.
