Pacific Northwest Forests Ecology Natural Resources – Lumber – Water – Recreation – Mining (minimal)

Pacific Northwest Forests Ecology Challenges in PNW Forests – Balancing uses of forests (resources versus recreation, wildlife, etc) – Conservation and management

Pacific Northwest Forests Ecology What is ecology? – Study of how organisms interact with each other and their environment

Pacific Northwest Forests Ecology What is ecology? – How does this involve agricultural science? Managing natural resources The effects of agriculture on the environment The effects of the environment on agriculture

Pacific Northwest Forests Ecology Communities – assemblages of different populations living in defined area – PNW Example: ? – Agricultural example: ?

Pacific Northwest Forests Ecology Ecosystem – collection of all the organisms that live in a particular place, and the nonliving environment – PNW Example: ? – Agricultural example: ?

Pacific Northwest Forests Ecology Biomes – group of ecosystems with the same climate and similar communities – PNW Example: ? – Agricultural example: ?

Gray Wolf

Pacific Northwest Forests Ecology Producers – Autotrophs – Photosynthesis, Chemosynthesis

Pacific Northwest Forests Ecology Consumers – Heterotrophs – Herbivores, carnivores, omnivores, detritivores/ decomposers

Pacific Northwest Forests Ecology Decomposers – Break down dead organisms into organic matter, nutrients, etc

Pacific Northwest Forests Ecology Food Chains – How energy is passed through an ecosystem

Pacific Northwest Forests Ecology Food Webs – Interactions between food chains

Pacific Northwest Forests Ecology Trophic Levels 1.Primary Producers 2.Primary Consumers 3.Secondary Consumers 4.Tertiary Consumers

Pacific Northwest Forests Ecology Energy Pyramid – Energy passing on to next trophic level – Only 10% of energy in a trophic level is transferred to the next trophic level

Assignment! 1.Find an article in a magazine or Capital Press that has to do with ecology and agriculture (some way ag and the environment are interacting!) 2.Read it. 3.Summarize it in 5-7 sentences (yes, 5-7) in your Lab Notebook. Make sure it is entered in the Table of Contents! 4.You will show this to Mr. Gary 5.THEN be ready to share this article with the class!
