  1. Ecology

  2. Defined: Studying how life interacts within the biosphere is called Ecology All life interacts within the biosphere Area within the deepest ocean trenches to the highest mountains What is Ecology? How do you interact with your environment?

  3. How does BHHS interact with the environment? Mrs. Moore(biology) runs & hikes

  4. And golfs….and surfs….and horseback trail rides.

  5. How does BHHS interact with the environment? Mr. Kobe (biology) rock climbs.

  6. How does BHHS interact with the environment? Mrs. Linden (nurse) horseback rides.

  7. How does BHHS interact with the environment? Mrs. Pincu (social studies) hikes.

  8. How does BHHS interact with the environment? and tubing. Mrs. Findley (dance) enjoys boating….

  17. How does BHHS interact with the environment? Mrs. Frutschy (social studies) snow boards… and falls a lot.

  18. How does BHHS interact with the environment? Ms. Boyarsky (librarian) hiking… Bird-watching… and kayaking.

  19. Levels of Ecology

  20. Defined: Group of one species living in the same area Population changes based on: Births, Deaths, Immigration, Emigration, Available resources Populations Click on information box

  21. School of Fish

  22. Herd of Buffalo

  23. Litter of Cats

  24. Flock of Birds

  25. Troop of Monkeys

  26. Pod of Whales

  27. Gaggle of Geese

  28. Smack of Jellyfish

  29. Murder of Crows

  30. Population Patterns • Populations go through 3 stages: • Slow growth • Population is slowly adapting to particular environment 2) Exponential growth • High birth rates due to abundant resources 3) Carry capacity • Defined: greatest number of individuals that the environment can sustain • Birth & death rates eventually balance • What stage is the human population in?

  31. What happens once we reach Carrying Capacity? Some populations stabilize for the long term Some populations experience a sharp decline called a “crash” Which will humans experience?

  32. Communities • Defined: Populations of many species living in the same area at the same time • Each organism has it own HABITAT • Habitat: Place where an organism lives • Each species has its own NICHE • Niche: The role/needs of a species • Ex: Termites return nutrients to the soil

  33. Defined: Communities of species interacting with the living & non-living Biotic (living) Factors: Animals: Mice, Reptiles, Insects Plants: Cactus, Flowers, Shrubs Abiotic (non-living) Factors: Sand, rocks, sunlight, climate, soil, water, etc… Ecosystem changes affect biodiversity Keystone species greatly alter ecosystems Ecosystems

  34. What is a Biome? • Defined: Large area with distinct climate, plant, and animal life • Climate factors: sun, rain, topography • Climate determines life

  35. The Biosphere • Defined: All organisms and the part of the Earth where life exists • Biosphere changes can affect life • Ex: More CO2 in the atmosphere… causes warmer temps

  36. 1) What is ecology? 2) What are two reasons that populations will increase? 3) What are two reasons that populations will decrease? 4) What are factors that control population growth called? 5) How does a population, community, ecosystem, biome, and biosphere differ? 6) What is a keystone species? 7) Place the levels of ecology in order from smallest to largest. Ecosystem, Population, Biosphere, Community, Biome Review
