Eco chapter 2 n

  1. 1. Chapter 2 Sustaining What the Environment Provides <ul><li>Objectives </li></ul><ul><ul><li>Described how the environment sustains life and the role of sustainable resource use </li></ul></ul><ul><ul><li>Name and explain the basic life needs that the environment provides for living organisms </li></ul></ul><ul><ul><li>Identify the three roles of humans in the environment </li></ul></ul><ul><ul><li>Describe the environment as home, including ecosystems, habitats, and food webs </li></ul></ul>
  2. 2. Terms <ul><li>Conservation </li></ul><ul><li>Ecosystem </li></ul><ul><li>Food </li></ul><ul><li>Food chain </li></ul><ul><li>Food web </li></ul><ul><li>Habitat </li></ul><ul><li>Hypothermia </li></ul><ul><li>Nutrient </li></ul><ul><li>Quality of life </li></ul><ul><li>Respiration </li></ul><ul><li>Shelter </li></ul><ul><li>Space </li></ul><ul><li>Sustainable agriculture </li></ul><ul><li>Sustainable development </li></ul><ul><li>Sustainable resource use </li></ul><ul><li>Sustaining life </li></ul><ul><li>Territory </li></ul>
  3. 3. Ask Yourself <ul><li>What do I need to live? </li></ul><ul><li>How does the environment help provide these needs? </li></ul>
  4. 4. Sustaining Life <ul><li>Organism require certain things to live that provided by the environment </li></ul><ul><li>Conditions are no longer provided, life may not be possible </li></ul><ul><li>Using resources so they last a long time </li></ul><ul><li>A person should use no more than is needed </li></ul><ul><li>No resource should be wasted </li></ul>
  5. 5. Sustainable Resource Use <ul><li>Is using resources so they last a long time </li></ul><ul><li>The resource is renewed, reused, and recycled as best as possible </li></ul><ul><li>Proper conservation practices are used </li></ul>
  6. 6. Sustainable Development <ul><li>Is to assure the best possible future </li></ul><ul><li>All development is carried out for the best long-term benefits to society </li></ul>
  7. 7. Sustainable Agriculture <ul><li>Involves using practices that assure the future ability to produce crop and livestock </li></ul><ul><li>Soil conservation practices are used to prevent loss and damage </li></ul><ul><li>Pesticides are used only as need and as approved </li></ul><ul><li>Wastes are properly disposed of and are not dumped on the land nor in streams </li></ul><ul><li>Area are provided for wildlife to live and grow </li></ul>
  8. 8. Having Good Quality of Life <ul><li>Quality of life is having a good environment in which to live </li></ul><ul><li>Environment provides for the needs of people </li></ul><ul><li>Example,they have clean air to breathe, unpolluted water to drink, and feel safe </li></ul>
  9. 9. Life Needs <ul><li>The major needs of living things are: </li></ul><ul><ul><li>Food </li></ul></ul><ul><ul><li>Water </li></ul></ul><ul><ul><li>Air </li></ul></ul><ul><ul><li>Space </li></ul></ul><ul><ul><li>Protection or shelter </li></ul></ul>
  10. 10. Food <ul><li>Food is nourishment and is need for energy and growth </li></ul><ul><li>Organisms obtain nutrients from food substances </li></ul><ul><li>Common nutrients are proteins, carbohydrates, fat, minerals, and vitamins </li></ul><ul><li>Damage to environment can result in food that is contaminated with dangerous materials </li></ul>
  11. 11. Water <ul><li>All living things required water to survive </li></ul><ul><li>Most nutrients dissolve in water to diffuse into the cells </li></ul><ul><li>If people do not get sufficient water, they become dehydrated </li></ul><ul><li>Dehydration is the removal of water from cells and organs </li></ul><ul><li>People get sick and required fluids back into system </li></ul>
  12. 12. Air <ul><li>Air is a mixture of gases that includes oxygen </li></ul><ul><li>Aerobic means to live where free oxygen is available </li></ul><ul><li>Anaerobic means to live where is not free oxygen </li></ul><ul><li>Human live in an environment with about 21 percent oxygen in the air </li></ul>
  13. 13. Space <ul><li>Space is the area around an organism that it uses for living </li></ul><ul><li>Space includes air, area for activity, food sources, and places for shelter and protection </li></ul><ul><li>Territory is the area an animal uses and protects as its own </li></ul>
  14. 14. Shelter and Protection <ul><li>Organisms sometimes need protection from the environment </li></ul><ul><li>Humans use clothing and housing to protect themselves from the weather </li></ul><ul><li>Greenhouse are used to provide a controlled environment for growing plants </li></ul>
  15. 15. Roles of Humans <ul><li>Humans have three roles: </li></ul><ul><li>Humans are resource users </li></ul><ul><li>Humans can make decisions about resource use </li></ul><ul><li>Humans can prevent waste </li></ul>
  16. 16. The Environment as Home
  17. 17. Ecosystem <ul><li>An ecosystem is all of the parts of a particular environment </li></ul><ul><li>It is a community of living organisms and nonliving materials </li></ul><ul><li>Ecosystems can be large or small </li></ul><ul><li>Ecosystems are continually changing </li></ul>
  18. 18. Habitat <ul><li>Habitat is the physical area where an organism naturally lives </li></ul><ul><li>It is the proper arrangement of four essential elements: food, water, shelter, and space </li></ul>
  19. 19. Energy Transfer <ul><li>Organisms must have energy to move about and carry out life functions </li></ul><ul><li>All of the energy in an ecosystem originates with the sun </li></ul><ul><li>Plants use sunlight and the process of photosynthesis to make food </li></ul>
  20. 20. Food Chain <ul><li>Energy is transferred from one organism to another in the food chain </li></ul>
  21. 21. Food Web <ul><li>A food web is all the interconnected food chains of an ecosystem </li></ul><ul><li>A plant may be eaten by more than one animal </li></ul><ul><li>The animals may be the prey of other animals </li></ul><ul><li>Finally, plants and animals die and their remains decay and are returned as nutrients to the soil </li></ul>
  22. 22. Tests <ul><li>How is quality of life affected when resources are damaged? </li></ul><ul><li>What are the major life needs of living organisms? </li></ul><ul><li>Why are these important? </li></ul><ul><li>What are the roles of humans in relating to the quality of the environment? </li></ul><ul><li>What relationships exist among ecosystems, habitats, and food chains? </li></ul>
