  1. Objectives 5/30/2014 HWK: Ecology Review Packet due Monday WARM UP: Please make sure you have your Botany Textbooks today. Please take a few minutes to clear out your Science Binders of anything from Botany and Paleontology. You may take your plant home with you today!!! GOAL: I will evaluate a partners Botany Packet and determine their grade. I will review Ecology and the various relationships between organisms and their environment. I will work on the “Ecology Review” AGENDA Grade Botany Packet Ecology Review Work on hwk or Stem Lab

  2. Levels of Organization

  3. Biodiversity- the diversity of life in an area. Biodiversity helps to keep ecosystems stable! A diverse ecosystem can prevent and recover from lots of disasters.

  4. Symbiosis: two organisms living close together. There are three types. 1) Mutualism 2) Commensalism 3) Parasitism

  5. Mutualism: both species benefit. Symbiosis:

  6. Commensalism: One member benefits & one is neither helped nor harmed. Symbiosis:

  7. Parasitism: One organism (parasite) lives on or in another organism (host) and harms it. Symbiosis:

  8. Carrying Capacity • Most living things produce more offspring than can survive. • A female frog lays 100’s of eggs in a small pond… Why is the pond not overrun with frogs??? • Populations can NOT grow indefinitely. • WHY??? LIMITING FACTORS!! • Carrying Capacity: The largest population that an environment can support over a long period of time.

  9. Producers:organisms that get energy from sunlight and make food. Ex: plants, plankton, algae, cyanobacteria, some bacteria

  10. Consumers: organisms that eat producers or other consumers. Primary: eat producers Secondary: eat primary consumers Tertiary: eat secondary consumers, etc.

  11. Figure this… 1 unit • Grass (at the base of the energy pyramid) has 1,000 units of energy available from the sun. • 90% is lost at each step of the pyramid. • Demonstrate how energy is passed by each of the following in the food chain/energy pyramid: grass, grasshoppers, snakes, hawks 10 units 100 units 1,000 units

  12. Shows how energy is lost as it is transferred from one organism to the next Energy Pyramid

  13. Food Webs- Complex web of interlocking food chains. Food Webs

  14. The Water Cycle • Define the following from your text book: • Evaporation, Transpiration, Condensation, Precipitation
