  1. The Science Test Georgia High School Graduation Test

  2. Ecology Individual Population Ecosystem

  3. What are the levels of organization of ecology? Population – group of a single species living in the same place Communities - group of interacting populations Ecosystem – the community and its environment Biome – group of ecosystems with the same communities Biosphere – the circle of life

  4. How does matter & energy flow in an ecosystem? • Food Chains – one path of energy flow • Food Webs – complex model that expresses all the possible feeding relationships in a community

  5. What are the trophic levels?

  6. Pyramid of energy, numbers, or biomass

  7. What are the relationships between organisms? • Predation + - Predator kills the prey for food • Competition - - both compete for same resources • Parasitism + - parasite lives in or on host • Mutualism + + symbiotic relationship in which both benefits • Commensalism + 0 symbiotic relationship in which one benefits and the other is not harmed

  8. What determines a Terrestrial Biome? • Climate – temperature and rainfall • 6 major biomes • Tundra • Coniferous Forest • Deciduous Forest • Grasslands • Desert • Tropical Rainforest

  9. What determines an aquatic biome? • Amount of light, oxygen and salinity • Lakes • Ponds • Wetlands • Marshes • Swamps • Estuaries • Coral Reefs • Deep Ocean

  10. Ecological Succession • Primary Succession: The process of creating life in an area where no life previously existed. • New volcanic islands, glacial retreat, rocks • Secondary Succession: The process of re-stabilization that follows a disturbance in an area where life has formed an ecosystem. • Abandoned farms, forest fires, volcanic eruptions
