2. 3-3 CYCLES OF MATTER MAIN IDEAS 1.Biogeochemical Cycle 2.Evaporation 3.Transpiration 4.Nutrient 5.Nitrogen Fixation 6.Denitrification 7.Primary Productivity 8.Limiting Nutrient 9.Algal Bloom Objective Describe & explain how matter cycles through the Biosphere identifying the affects of nutrient limitations using highlighted diagrams & written explanations. IaN pg. 57

3. Biogeochemical Cycles = the interdependence of matter between the environment & organisms.

4. I. Recycling in the Biosphere A. Energy is not recycled, it flows from the sun up each level of the food web. B. Matter [atoms] is recycled endlessly though the biosphere.

5. II. Water Cycle p. 75 in text

6. III. Nutrient Cycles (Carbon, Nitrogen & Phosphorous) A. Food [nutrients] we eat contains energy, but it also contains the chemicals [atoms] that are the building blocks of proteins, lipids, carbohydrates, and nucleic acids. B. Atoms are not used up like the energy, instead they are recycled through the biosphere.

7. 1. Carbon Cycle Where is carbon stored? a. In the atmosphere b. In the ocean c. Underground in rocks [calcium carbonate] and as fossil fuels d. In living organisms such as trees/forests https://www.youtube.com/watch?v=2D7hZpIYlCA

8. Carbon Cycle p. 77 in text

9. 2. Nitrogen Cycle & Bacteria a. Nitrogen fixation i. Nitrogen leaves atmosphere and enters soil. ii. Bacterial and Atmospheric b. Denitrification i. Bacteria converts nitrogen back to a gas and enters the atmosphere. c. Nitrification i. Bacteria converts nitrogen in soil into different forms.

10. Nitrogen Cycle

11. Phosphorous Cycle https://www.youtube.com/watch?v=leHy-Y_8nRs

12. IV. Nutrient Limitation A. Ecosystems can be lacking in a single nutrient = 1. Ocean ecosystems are usually limited by Nitrogen 2.Freshwater ecosystems are often limited by Phosphorous B. = rate at which organic matter is produced. Dependent on Nutrient availability. Limiting Nutrient Primary Productivity

13. V. Algal bloom A.Rapid growth of producers/algae can be caused by the addition of a limiting nutrient to an ecosystem. 1. Runoff of fertilizers used for agriculture.
