Biogeochemical Cycles

           Our plants have gone from seeds to growing plants. They have gotten very big. They have large leaves and are taller then they were before. When our plants are watered, they will absorb the water through their roots. The rest of the water will evaporate from the soil. Our plants will use photosynthises to suck carbon dioxide out of the air. When they take in carbon dioxide, they will release oxygen into the air. Nitrogen is a very important element to a plant. It helps them carry out many  functions of life. The plants absorb nitrogen from the soil. These cycles help our plants and other plants survive.
