3. The Water Cycle

4. The Water Cycle Continued
The Sun's heat provides energy to evaporate water from the Earth's surface (oceans, lakes, etc.). Plants also lose water to the air (this is called transpiration). The water vapor eventually condenses, forming tiny droplets in clouds.

5. Water Continued
When the clouds meet cool air over land, precipitation (rain, sleet, or snow) is triggered, and water returns to the land (or sea). Some of the precipitation soaks into the ground. Some of the underground water is trapped between rock or clay layers; this is called groundwater. But most of the water flows downhill as runoff (above ground or underground), eventually returning to the seas as slightly salty water.

6. The Carbon Cycle

7. The Carbon Cycle lets watch The circle of life!

8. The Carbon Cycle
Carbon enters the atmosphere as carbon dioxide from respiration (breathing) and combustion (burning). 
Carbon dioxide is absorbed by producers (life forms that make their own food e.g. plants) to make carbohydrates in photosynthesis.
These producers then put off oxygen.

9. The Carbon Cycle continued
Animals feed on the plants. Thus passing the carbon compounds along the food chain.
Most of the carbon these animals consume however is exhaled as carbon dioxide.
This is through the process of respiration. The animals and plants then eventually die.

10. The Nitrogen Cycle!

11. The Nitrogen Cycle

12. The Nitrogen Cycle
Step 1:  A special type of bacteria called nitrogen fixing bacteria take in atmospheric nitrogen and produce ammonia (NH3).
Step 2:  Other bacteria use this ammonia to produce nitrates and nitrites, which are nitrogen and oxygen containing compounds.
Step 3:  The nitrates and nitrites are used by plants to make amino acids which are then used to make plant proteins.

13. The Nitrogen Cycle continued
Step 4:  Plants are consumed by other organisms which use the plant amino acids to make their own.
Step 5:  Decomposers convert the nitrogen found in other organisms into ammonia and return it to the soil. A few of these type of bacteria return nitrogen to the atmosphere by a process called denitrification, however this amount is small.
