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

3 Carbon Dioxide + Water + Sun’s Energy --> Oxygen + Sugar PHOTOSYNTHESIS AND RESPIRATION ARE PARTNERS! Photosynthesis: Producers CONVERT solar energy to 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 RESPIRATION: Animals (and plants) use Oxygen and Sugar to make energy! CO 2 is a product of this reaction and RECYCLES the CO 2 in the air. PHOTOSYNTHESIS AND RESPIRATION ARE PARTNERS! Carbon Dioxide + Water + Sun’s Energy --> Oxygen + Sugar Oxygen + Sugar--> water+ carbon dioxide + chemical energy

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

6 Carbon conundrum Sources of atmospheric CO 2 are increasing SINKS (ways to remove CO 2 ) from the atmosphere are DECREASING We therefore have an excess CO 2 in our atmosphere This creates a blanket around the earth that traps solar energy (GREENHOUSE EFFECT)

7 Widespread Pollution Greenhouse Effect

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

10 THE NITROGEN CYCLE AMMONIA (NH 3 ) is a WASTE product of animals Dead animals and plants release N into soil Bacteria convert (change) Ammonia into Nitrates Bacteria convert (change) Atmospheric Nitrogen and Nitrites into Nitrates Some Nitrates leech or “leak” out of the soil into water

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

Cycles of Nature Matter, as well as energy, moves through an ecosystem and is constantly recycled. Nitrogen, water, oxygen and carbon are cycled globally.
