Unit 5: Lesson 1: Assignment
Every organism in an ecosystem is affected by the other organisms in the community it lives in. Make a sample community and complete all of the following points about your community:
1. Define "trophic levels". Provide a specific example of four species and describe their trophic-level relationships.
2. Trace energy flow through your sample community.
3. What factors influence the diversity of the species that make up your community?
4. Research the following: In your local community or province, find an example of two organisms that have co-evolved. Describe how both organisms have changed, and explain the benefits and drawbacks for each organism.
Unit 5: Lesson 4: Assignment
1. Draw a flow chart to show how the domestication of plants and animals led to growth of the human population.
2. According to the demographic transition model, why might some developing countries stay in the transitional stage and maintain a high rate of population growth?
3. What does an ecological footprint measures?
How does limiting the use of plastic bags help reduce the ecological footprint? Be sure to include economical and environmental perspectives.
4. The human population is increasing rapidly. Describe four ways that it is overburdening the Earth's natural resources?
