Unit 8: Ecology
This unit will allow each student to:
a. gain a better understanding of ecology and its principles
b. gain a better understanding of the organization of an ecosystem
c. gain a better understanding of how populations interact within an ecosystem
d. continue making proper scientific measurements and calculations
e. define and properly use all vocabulary
f. properly apply all terms and concepts in describing/explaining real world examples
g. make and interpret scientific graphs and diagrams
h. teach someone else the concepts discussed
i. practice proper laboratory safety
This will be accomplished by each student that is able to:
1. identify the levels of organization within the biosphere
2. explain the difference between abiotic factors and biotic factors
3. differentiate between an organisms habitat and niche
4. identify the three different types of symbiotic relationship
5. describe the flow of energy in an ecosystem by creating a food web and identifying various food chains
within a given food web
6. identify the ultimate energy source for photosynthetic producers
7. identify the three types of ecological pyramids, describe the trophic levels represented in each, and the
flow of energy/biomass/number in each
8. trace the path of essential nutrients in each of the biogeochemical or matter cycles
9. explain the importance of nutrients to living organisms
10. recognize how unfavorable abiotic and biotic factors affect a species
11. describe how ranges of tolerance affect the distribution of organisms
12. compare and contrast primary and secondary succession and sequence their stages
13. relate latitude and the 3 major climate zones
14. identify the location and describe the characteristics of the terrestrial biomes
15. distinguish between the three types of aquatic ecosystems
16. identify the zones in an open ocean
17. recognize that freshwater biomes are characterized by depth and water flow
18. identify limiting factors to population growth
19. distinguish between and exponential growth or J-curve graph and a logistic growth or S-curve graph
20. analyze a human age diagram
21. predict the consequences of continued population growth
22. identify the 3 types of biodiversity, the importance of biodiversity, threats against biodiversity,
conservation attempts to protect biodiversity
