1. Biogeochemical Cycles SES1e

2. Recycling in the Biosphere VOCABULARY  Biogeochemical Cycles – Process in which elements, chemical compounds, and other forms of matter are passed from one organism to another and from one part of the biosphere to another.

3. Cycles in the Ecosystem Topic: Cycles in the Ecosystem What causes matter to cycle in the ecosystem? Information: Interactions of abiotic factors and biotic factors. Interactions of abiotic factors and biotic factors. Nutrients are passed between organisms and the environment through biogeochemical cycles Nutrients are passed between organisms and the environment through biogeochemical cycles

4. Cycles of Matter Topic: Cycles of Matter How does energy flow differ from cycles? What are the cycles of matter? Information: Unlike the one-way flow of energy, matter is recycled within and between ecosystems.  Carbon Cycle  Phosphorus cycle  Sulfur cycle  Nitrogen cycle

5. CARBON Cycle

7. Carbon Cycle Topic: Carbon Cycle What moves carbon through its cycle? Information: 1.Carbon is cycled through the ecosystem by the biological processes of photosynthesis, cellular respiration and decomposition. 2.Also by the geological processes of volcanic activity and erosion, and human activities such as mining and burning of fossil fuels.

8. Phosphorus Cycle

9. Topic: Phosphorus Cycle Where is Phosphorus in our biosphere? Why is it essential to living organisms? How do we get the phosphorus we need? Information:  Phosphorus remains on land and in ocean sediments as inorganic phosphates and is cycled through the ecosystem as plants absorb phosphates in the soil  Phosphorus is needed by organisms as a component of DNA.  The phosphate moves from producer to consumer in the food web

11. Sulfur Cycle Topic: Where is Sulfur in our biosphere? Why is it essential to living organisms? How does it get there? Information:   Sulfur is mainly found on Earth as sulfates in rocks or as free sulfur   It kills molds and bacteria.   Sulfur is released into the atmosphere through the burning of fossil fuels

12. The Nitrogen Cycle

13. VOCABULARY  Nitrogen Cycle – nitrogen moves slowly through the cycle and is stored in reservoirs such as the atmosphere, living organisms, soils, and oceans along its way.

14. Nitrogen Cycle Topic: Nitrogen Cycle Where is all the nitrogen on Earth? So, how do we get the nitrogen we need? Information: Approximately 80% is in the atmosphere. It is not useable for living things.  Plants get nitrogen from soils and water.  Animals get nitrogen from eating plants or other animals that contain molecules of nitrogen.

15. Nitrogen Cycle Topic: Information Pages: How does the Nitrogen get there? When organisms die, their bodies decompose bringing the nitrogen into the soil on land or into the oceans.
