  1. Organization of Life

  2. Defining an ecosystem • Examples: • Oak forest • Coral Reef • Vacant lot • Basically, all of the organisms living together in a physical environment

  3. Components of an Ecosystem • Energy • Minerals and nutrients • CO2 • O2 • H2O • Living organisms

  4. Living and nonliving • Use the terms biotic and abiotic instead • Biotic factors: living parts of ecosystem • EX: plants and animals • Can be dead or living • Can be whole or pieces • Waste counts too!

  5. Living and nonliving • Abiotic: nonliving parts of ecosystem • EX: air, water, rocks, sand, light, temperature

  6. Classify them! • In the space provided, write “B” next to biotic factors and “A”next to abiotic factors. • ______ animals • ______ temperature • ______ air • ______ dead parts of organisms • ______organisms’ waste products • ______water • ______rocks • ______plants • ______sand • ______dead organisms • ______light

  7. From Small to Big: Organizing Life • An organism is only 1 creature • A species is all of the same type of organism that can mate

  8. From Small to Big: Organizing Life • A population is a group of the same species living in the same place at the same time • A community is a location that has more than one population in it

  9. Habitats • Different places in which animals and plants live • All have different traits • Organisms do well in their native habitats
