Understanding Natural Resources and Ecosystem Dynamics

This chapter explores the complex interactions within ecosystems, highlighting key concepts such as communities, populations, and ecological succession. It examines the impact of human activities, including deforestation and dam construction, on ecosystems. Additionally, the chapter differentiates between nonrenewable resources like fossil fuels and renewable resources such as solar and wind energy. It addresses environmental issues like pollution, global warming, and eutrophication while emphasizing the importance of recycling and alternative energy sources for sustainable development.

  1. Chapter #19 Using Natural Resources

  2. Chapter 19.1 Notes • Ecosystem all of the living and nonliving things in a certain place. (Forest) • Community- (Living things) all of the animals and plants living in one area within an ecosystem. • Population- one specific type of living thing. (Maple Trees)

  3. Succession is the gradual repopulation of a community by different species over a period of time.

  4. Changes to ecosystem by humans can be positive or negative. • The deforestation of the rain forest • Building Dams • Bringing to the US new plants and animals

  5. Chapter 19.2 • Fossilfuels- are any fuels formed from the remains of ancient plant and animal life • Nonrenewable resources- any resources that are used faster than they can be replaced. Estimated that gas will run out in 2045, oil 2055, coal 2295. Coal Oil Gasoline Natural gas

  6. Renewableresources-any resources that can be continually replaced. • Sun • Wind • Water • Geothermal

  7. Alternative Energy Sources Solar Windmills Water in Dams Nuclear Energy Geothermalenergy- the energy drawn from heated water within Earth’s crust.

  8. Chapter 19.3 Notes • Pollution- the contamination of the air, water, or soil (land). • Globalwarming- an increase in earth’s temperature due to an increase in greenhouse gases • Eutrophication- an increase in the amount of nutrients, such as nitrates, in the environment

  9. Recycling- the process of breaking down discarded material for reuse in other products
