    Circumstances or conditions that surround an organism or groups of organisms. OR The complex of social or cultural conditions that affect an individual or community
  2. What is the world’s human population?
    6.5 Billion
  3. What are the 4 distinct stages of the
    environmental movement?
    • - Pragmatic Resource Conservation
    • - Moral and Aesthetic Nature
    • Preservation
    • - Concern about Health and
    • Ecological Damage
    • - Global Environmental Citizenship
  4. What did John Muir believe?
  5. What did Rachel Carson do?
  6. What percentage of the world’s population is the US population?
    4.6%
  7. What percentage of the world’s oil do we consume?
    25%
  8. How much toxice waste do we produce?
    50%
  9. Sustainable development is:
  10. Environmental Racism is:
    An inequitable distribution of environmental hazards based on race.
  11. Science is:
    • - a methodical, logical process for producing knowledge about
    • natural phenomena

    - a cumulative body of knowledge produced by scientists

    - a process based on careful observation and hypothesis testing
  12. Scientists strive for 2 things:
    • accuracy - correctness of measurements
    • reproducibility - repeatability of results

    repeating studies or tests is called replication.
  13. Deductive reasonsing is:
    logical reasoning from general to specific
  14. Inductive reasoning is:
    reasoning from many observations to produce a general rule
  15. A system is:
    a network of interdependent components and processes with materials and energy flowing from one component to another. Systems are a central concept in environmental science.

    Examples: ecosystems, climates systems, geologic systems, economic systems
  16. An open system is:
    system that takes inputs from its surroundings
  17. A closed system is:
    self contained and receives no inputs of energy or materials from the outside
  18. Ecology is:
    the scientific study of the relationship between organisms and their environment.
  19. Matter is:
    Matter - everything that has mass and takes up space

    Matter is neither created nor destroyed but rather re-cycled over and over. The atoms in your body may have been in a dinosaur.

    The idea that matter cannot be destroyed but is simply transformed from one form to another is termed conservation of matter.
  20. Three States of Matter:
    Solid, Liquid, Gas
  21. Elements are:
    substances that cannot be broken down into simpler forms by ordinary chemical reactions

    • 118 elements, but just four (oxygen, carbon, hydrogen and nitrogen) make up 96% of the mass of living
    • organisms
  22. Atoms are:
    smallest particles exhibiting characteristics of the element.
  23. Atoms are composed of:
    Protons (+) - Neutrons -Electrons (-)

    Protons and neutrons are in the nucleus; electrons orbit
  24. Molecules are:
    two or more atoms joined together
  25. Oxidation is:
    When an atom gives up one or more electrons, it is oxidized.
  26. Ions are:
  27. Acids are:
  28. Organic Compounds are:
  29. Cells are:
  30. Enzymes are:
  31. The First Law of Thermodynamics states:
  32. Solar energy is essential for 2 reasons:
  33. Photosynthesis captures ______ while cellular respiration releases ______.
  34. The definition of Species.
  35. A biological community is:
  36. An ecosystem is:
  37. Give an example of a producer:

  39. Give another word and example of a secondary producer:
  40. Why are high levels of phosphorus dangerous to Lake Michigan?

  57. Density-dependent population growth is:
  58. List the 4 factors that affect growth rate:
  59. List the 4 factors that regulate population growth:
