  1. ECOLOGY Introduction

  2. Ecology is about Cause and Effect • Looks at the • Interaction & • Interdependence Of organisms to each other and to their environment. • We have studied • Genus and species • populations

  3. Expanding outward to…

  4. ECOLOGY • “ECO” – “the Environment” /”nature” • “OLOGY”- study of • The study of the interactions between organisms within a particular area.

  5. Ecology vocabulary words: Individual – single organism. Population – group of individuals who can mate (species). Community – Groups of different populations within a particular area. Ecosystem – Living and non-living things within a particular area. Biome– Groups of similar ecosystems living together. Biosphere– THE WHOLE WORLD

  6. Ecosystem Self-sustaining collection of organisms and their physical environment Biotic – living things Abiotic – non-living things

  7. Biome Major communities that occur over wide areas on land Scientists have divided the Earth into 7-9 major biomes Climate – temperature and precipitation. Climate dictates biomes.

  8. Major Biomes of the Earth

  9. Food Chains PRIMARY PRODUCERS In your groups define using two to three words Niche-Animal’s role in the ecosystem. Types of niches: Herbivore Omnivore Carnivore Predator Prey Decomposer Scavenger Eats Producers Eats consumers and producers Eats only live animals. The hunter The hunted Break down dead and organic material Eats animals that are dead/ have been killed

  10. FOOD CHAIN SETS:In your group • Put your groups set in order • Check another groups set • Draw one of the food chains! THE ARROW IN A FOOD WEB SHOWS WHERE THE ENERGY GOES TO!!

  11. Arrows on the food web showwhere the energy goes.

  12. Various Relationships Both organisms benefit • Mutualism • Neutralism • Competition& Predation • Commensalism • Parasitism Neither organism benefits One organism out runs another or takes over an area One benefits, nothing happens to the other. Host does not benefit, ONLY parasite does

  13. Match the situation to one of the relationships
