Nutrient Cycles: Photosynthesis, Respiration, Carbon Cycle, and Nitrogen Cycle

Learn about the important processes of photosynthesis and respiration, and how they work together to cycle nutrients in ecosystems. Explore the carbon cycle, including the impact of combustion and the greenhouse effect, as well as the nitrogen cycle and its role in soil and water. Understand the ways in which nutrients are recycled to support new life.

Presentation Transcript

  1. NUTRIENT CYCLES Nutrients are chemicals that organisms need to survive. Example – All organisms need Nitrogen to make protein NUTRIENTS must be RECYCLED when animals and plants die so that new animals and plants can get nutrients too.

  2. PHOTOSYNTHESIS AND RESPIRATION ARE PARTNERS! Photosynthesis: Producers CONVERT solar energy to sugar. Carbon Dioxide + Water + Sun’s Energy -->  Oxygen + Sugar

  3. PHOTOSYNTHESIS AND RESPIRATION ARE PARTNERS! Photosynthesis: Producers CONVERT solar energy to sugar. Carbon Dioxide + Water + Sun’s Energy -->  Oxygen + Sugar Oxygen + Sugar-->  water+ carbon dioxide + chemical energy RESPIRATION: Animals (and plants) use Sugar as a source of energy for growth, movement, repair, and reproduction

  4. PHOTOSYNTHESIS AND RESPIRATION ARE PARTNERS! Carbon Dioxide + Water + Sun’s Energy -->  Oxygen + Sugar Oxygen + Sugar-->  water+ carbon dioxide + chemical energy RESPIRATION: Animals (and plants) use Oxygen and Sugar to make energy! CO2 is a product of this reaction and RECYCLES the CO2 in the air.

  5. THE CARBON CYCLE: How carbon is balanced in ecosystems Combustion means Burning of Fossil Fuels Decomposed organisms are “storage” for carbon in the soil

  6. Carbon conundrum • Sources of atmospheric CO2 are increasing • SINKS (ways to remove CO2) from the atmosphere are DECREASING • We therefore have an excess CO2 in our atmosphere • This creates a blanket around the earth that traps solar energy (GREENHOUSE EFFECT)

  7. Greenhouse Effect Widespread Pollution

  8. The OCEAN is an important part of the carbon cycle too.

  9. THE NITROGEN CYCLE Dead animals and plants release N into soil AMMONIA (NH3) is a WASTE product of animals Bacteria convert (change) Atmospheric Nitrogen and Nitrites into Nitrates Some Nitrates leech or “leak” out of the soil into water Bacteria convert (change) Ammonia into Nitrates

  10. Weathering or ‘wearing down’ of rocks Runoff into water Phosphate in the water

  11. Weathering or ‘wearing down’ of rocks Runoff into water Phosphate in the water SEDIMENTATION (animals, plants and rocks settle to the ground) making new rocks

  12. THE NITROGEN CYCLE
