    • Zebra mussels are a great threat to the Great Lakes.
    • Compete with fish for plankton
    • Clarify water, cause plants to grow
  • 3.
    • The soil, air, and surface where living things can grow
  • 4.
    • Organism Human being
    • Population Family
    • Community Town
    • Ecosystem People and buildings
    • Biome State of PA/US
    • Biosphere World/Planet
  • 5.
    • Large habitat
      • Atlantic Ocean
      • Forests
      • Jungles
    • Small habitat – “microhabitat”
      • Rotting Log
      • Large Intestine
      • Riffle, Run, or Pool in a Stream
  • 6.
    • Living components of an ecosystem
      • Competing trees
      • Predators
      • Viruses
      • Bacteria
      • Pathogens
  • 7.
    • Non-living components in an ecosystem
      • Sunlight
      • Air
      • Water
      • Minerals
  • 8.  
  • 9.
    • Much more complex
    • Represent actuality
  • 10.
    • Any given environment can only support so many organisms
    • If a population reaches its max, organisms will:
      • Die
      • Move
      • Adapt
  • 11.
    • Eventually the environment will no longer support any more individuals
    • The graph is in the shape of an S: “S-Curve”
  • 12.
    • The role an organism plays in an ecosystem
    • Two organisms CANNOT occupy the same niche
    • If they did, they would compete for resources
      • Die
      • Move
      • Adapt
  • 13.
    • Homeo = Same, Stasis = State of activity
    • A “steady state” that an ecosystem is normally in before a disruption
  • 14.
    • Fire
    • Tornado
    • Volcano
    • Humans
    • Hurricanes
    • Tsunami
  • 15.
    • Geographic areas with similar soil and climates
    • Have similar species adaptations
    • Common plants and animals characteristic of those climates
  • 16.
