  1. Organisms and Their Environment

  2. Bell Ringer • Are there other houses/buildings around here? • What is it called when a bunch of houses are near each other together? • What do you call an area with a bunch of neighborhoods together? • Name 3 biotic factors and 3 abiotic factors in Cook County.

  3. Today’s objective • SWBAT list and describe/define the levels of organization

  4. Why are we studying the environment? -Understanding what affects the environment is important because it’s where we live!

  5. Just like we organize houses into neighborhoods and neighborhoods into towns, and towns into counties, scientists group living and non-living things in several categories called levels of organization.

  6. II. Levels of Organization in Ecology The last level of organization is biosphere- consists of all life on Earth and all parts of the Earth in which life exists, including land, water, and the atmosphere.

  7. II. Levels of Organization in Ecology The fifth level of organization is Biomes- a group of ecosystems that share similar climates and typical organisms. Ex: Marine biome – Tropical isle of Bikini Atol in Pacific Ocean, (Bikini Bottom boxed)

  8. II. Levels of Organization in Ecology The fourth level of organization is Ecosystems- All the organisms that live in a place, together with their physical environment.

  9. II. Levels of Organization in Ecology The third level of organization is Communities: All the organisms that live in a place, together with their physical environment. Ex: Spongebob, his neighbors, friends, employer

  10. II. Levels of Organization in Ecology The second level of organization is Population- a group of individuals that belong to the SAME species and live in the same area. Ex: Spongebob and his parents

  11. POPULATION A species is a group of organisms that can have fertile offspring. What does “species” mean?

  12. II. Levels of Organization in Ecology The first level of organization is Individual organism (species)- a group of similar organisms that can breed and produce fertile offspring. Ex: Spongebob is a sponge

  13. II. Levels of Organization in Ecology Does the number of individuals go up or down as we go from biosphere to oragnism? Biosphere (biggest group) Biome Ecosystem Community Population Organism (smallest group)

  14. III. Biotic vs Abiotic Factors Biotic = living (BIO = life) Biotic factors- any living part of the environment with which an organism might interact. For Spongebob this would include various fishes, crabs and sea creatures, the jellyfish, Gary, Plankton

  15. III. Biotic vs Abiotic Factors Abiotic = non-living Abiotic factors- any nonliving part of the environment, such as sunlight, heat, water currents, soil type. For Spongebob this would be various things like bubbles, the water, sand, buildings, boatmobiles
