| Ecological Principles:
Learner objectives: The student will
1. Define ecosystem and describe an ecosystem (at Bay Tree
Beach, Back Bay, False Cape...).
2. Distinguish abiotic factors from biotic factors.
3. Define ecology.
4. Explain the significance of sustainable development.
5. Contrast biotic potential with environmental resistance.
6. Explain the concept of tolerance and give examples from
the field.
7. Apply Leibig’s law of the minimum to choosing fish to
bring back from the field.
8. Determine methods to assess sustainable development.
9. Apply our research to evaluation of sustainable
development.
10. Analyze some of the categories of interactions occurring
in the ecosystem.
11. Examine trophic structure of a community or an ecosystem
and suggest methods to study
trophic structure.
12. Identify relationships within communities.
13. Distinguish between intraspecific and interspecific
competition and give examples from the
field.
14. Distinguish between abundance and diversity.
15. Explain how the relationship between abundance and
diversity are
related to perpetuation of an ecosystem (sustainable
development).
16. Describe the two life history strategies and relate these
life styles to niche and habitat.
17. Explain the significance of biogeochemical cycling to the
concept of sustainable development.
18. Describe C, N, and P biogeochemical cycles.
