Unit 8: Ecology

Ecology Song





Relevant Standard(s):

SB4. Students will assess the dependence of all organisms on one another and the flow of energy and matter within their ecosystems.

a. Investigate the relationships among organisms, populations, communities, ecosystems, and biomes.

b. Explain the flow of matter and energy through ecosystems by

• arranging components of a food chain according to energy flow.

• comparing the quantity of energy in the steps of an energy pyramid.

• explaining the need for cycling of major nutrients (C, O, H, N, P).

c. Relate environmental conditions to successional changes in ecosystems.

d. Assess and explain human activities that influence and modify the environment such as global warming, population growth, pesticide use, and water and power consumption.
Unit 7 Overview

Big Ideas:

1. there is a relationship between an individual, a population, a community, an ecosystem, and a biome. 
2. all organisms are interdependent. 
3. there are relationships between living and nonliving factors. 
4. energy and matter abide by the laws of conservation of energy and matter within an ecosystem. 
5. environmental conditions affect changes in the ecosystem. 
6. human activities can have a direct and indirect effect on every level of organization in an environment.

Essential Questions:

1. How does energy flow through terrestrial and aquatic ecosystems? 
2. How do human actions impact ecosystems?
3. What are the levels of ecological organization? 
4. How do biogeochemical cycles more essential elements (C, O, H, N, P) between biotic and abiotic components of the ecosystem? 
5. How do ecosystems progress through primary and secondary succession? 
6. What abiotic factors limit the distribution of organisms? 
7. How much energy is transferred between trophic levels? 
8. How do human activities modify the environment? 9. What types of symbiotic relationships exist among organisms?
