Unit 6 populations and ecosystem lesson12 population and ecosystems portfolio

Answer 1

As an AI language model, I don't have access to your school's curriculum and specific requirements for your portfolio. However, I can give you some general ideas and suggestions for what you might include:

1. Population Growth Model: Create a population growth model for a particular species within an ecosystem. Use data on birth and death rates, as well as various environmental factors that affect the population size such as food and water availability. Graph the simulation of the population over time.

2. Endangered Species Report: Choose an endangered species within an ecosystem and research their habitat, daily life, and environmental threats. Discuss the reasons behind its population decline and the efforts taken to protect this species. Suggest some ways in which humans can contribute to the conservation of such endangered species.

3. Ecological Succession Study: Select an example of ecological succession, such as a forest fire. Research the ways that it can impact an ecosystem and its populations. Analyze the process of primary and secondary succession, and discuss the roles of different species in this regeneration process.

4. Food Chain Food Web Project: Create a food web for an ecosystem and explain how the different populations within it interact. Choose a particular species within the food web and explain its role within the food chain and how it contributes to the overall health of the ecosystem.

5. Pollution Effects Research: Choose a form of pollution (e.g., air, water, or soil pollution) that affects an ecosystem's populations. Examine how it arises and its impact on the environment within a particular area. Suggest some possible solutions to mitigate its effects.

6. Human Population Growth Model: Create a population growth projection model for the human population. Analyze the impacts of human population growth on ecosystems and the immediate potential consequences of the population's growth.

7. Restoration Study: Choose an ecosystem that has been damaged because of human activity, such as deforestation. Research the methods used to restore the ecosystem to its former state and the positive impacts of the restoration of such ecosystems.

Remember, your portfolio should include research, analysis, and your own personal reflection and ideas about the topics you choose. Make sure you document and cite all research sources in an appropriately formatted way.
