    •  
      • Zebra mussels are a great threat to the Great Lakes.
      • Compete with fish for plankton
      • Clarify water, cause plants to grow
      • The soil, air, and surface where living things can grow
      • Organism Human being
      • Population Family
      • Community Town
      • Ecosystem People and buildings
      • Biome State of PA/US
      • Biosphere World/Planet
      • Large habitat
        • Atlantic Ocean
        • Forests
        • Jungles
      • Small habitat – “microhabitat”
        • Rotting Log
        • Large Intestine
        • Riffle, Run, or Pool in a Stream
      • Living components of an ecosystem
        • Competing trees
        • Predators
        • Viruses
        • Bacteria
        • Pathogens
      • Non-living components in an ecosystem
        • Sunlight
        • Air
        • Water
        • Minerals
    •  
      • Much more complex
      • Represent actuality
      • Any given environment can only support so many organisms
      • If a population reaches its max, organisms will:
        • Die
        • Move
        • Adapt
      • Eventually the environment will no longer support any more individuals
      • The graph is in the shape of an S: “S-Curve”
      • 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
      • Homeo = Same, Stasis = State of activity
      • A “steady state” that an ecosystem is normally in before a disruption
      • Fire
      • Tornado
      • Volcano
      • Humans
      • Hurricanes
      • Tsunami
      • Geographic areas with similar soil and climates
      • Have similar species adaptations
      • Common plants and animals characteristic of those climates
