Ecological Organization

  1. 1. Catalyst:  Write down your answer in the Monday Catalyst box.  Write your definition of ecology and what is entails as a science.
  2. 2. Ecology I will be able to identify the different levels of organization in Ecology and identify what shapes an ecosystem.
  3. 3. Interactions and Interdependence  Ecology is the study of the interactions of organisms with their physical environment and with each other.  The study of ecology ranges from the study of an individual organism to populations, communities, ecosystems, biomes, and to the entire biosphere.
  4. 4. Levels of Organization-from smallest to largest  Organism: an individual.  Organisms belong to a species. Species are groups of organisms so similar to one another that they can breed and produce fertile offspring.  Population: groups of individuals that belong to the same species and live in the same area (throwback to last unit!)  Ex: pod of whales, pride of lions
  5. 5. Levels of Organization-from smallest to largest  Community: consists of all the organisms living in one area.  Ex: Pride of lions, hyenas, antelope, grass, etc. What do all of these things have in common?  Ecosystem: includes all of the organisms in a given area as well as the abiotic factors (nonliving) with which they interact.  Ex: pride of lions, rocks, water, grass, antelope, soil, sunlight, wind, etc.
  6. 6. Levels of Organization-from smallest to largest  Biomes: a particular physical environment that contains a characteristic assemblage of plants and animals.  Ex: tropical rain forest, tundra, desert, etc.  Biosphere: contains the combined portions of the planet in which all of life exists. Includes the land, water, and atmosphere.

  10. 10. Memory Monday  At the very core of EVERY organisms interaction with its environment, is its need for energy.  Where does it come from?  Autotrophs!  What are they?  Organisms that capture sunlight and use that energy to produce chemical compounds for food.
  11. 11. Memory Monday! Continued…  Who gets the energy next?  Heterotrophs!  They rely on other organisms for their energy (Consumers)  3 kinds!  Herbivores, Omnivores, and Carnivores.
  12. 12. Memory Monday continued!  Energy flows one way in a ecosystem. From the sun, to autotrophs, to heterotrophs.  Food chains: very simple chain of organisms showing the flow of energy.  Food Webs: More complex, consist of several food chains, even include decomposers-detritivores  Ecological Pyramids: 3 kinds!  Energy pyramids: Shows the relative amount of energy available at each trophic level.  Biomass pyramid: represents the amount of living organic matter at each trophic level.  Pyramid of numbers: shows the relative number of individual organisms at each trophic level.
