Science Standard 6d: Biogeochemical Cycles/ Nutrient Cycles Ch. 3 Sec. 3 La Serna High School Mrs. McElroy and Ms. G 2009.
Chapter 3. The study of interactions between organisms and their environment.
Nutrient cycles Ecosphere Photo Earth Photo Nutrient cycles Nutrient cycles, or “biogeochemical cycles,” involve natural processes that recycle nutrients.
THE NITROGEN CYCLE Explore the cyclical interconversion of N 2 and its compounds via covering: Nitrogen fixation Nitrification Denitrification Nitrate.
Cycles That Occur in Nature. Water cycle Moves between atmosphere, oceans & land 1 – water evaporates from the ocean 2 – water also evaporates.
Ecosystem Function Nutrients & Nutrient Cycling. Ecosystem function and nutrients Elements that are required for the growth, maintenance and reproduction.
Primary Production. Production: Formation of Organic Matter Autotrophic Organisms (Plants, algae and some bacteria) –Photosynthesis –Chemosynthesis CO.
