Biogeochemical Cycles and Our Plants

      This week our plant has grown at least six more inches and had grown outward probably twice as much since we last checked it. . The leaves were more spread out, but it looked like a bug had used the collard leaves at food, and the veins were standing out much more than they were.  The whole plant was a much darker green.       Our plant, the collard, contributes the the movement of water in the biosphere by absorbing water and breaking it apart the releasing the oxygen back into the air. The plant then uses the new hydrogen to grow bigger and taller and get more leaves.  This is exactly what happened to our collard plants ever since we planted a few weeks back.       Also, the collard plant helps move carbon around the atmosphere.  The plant takes the carbon from the sun using photosynthesis.  The plant then stores the carbon and uses it to grow. When the plant dies, it will be buried, then turn into fossil fuels, and when we burn these fossil fuels in the future, carbon is released into the air, and the cycle continues        Another cycle our collard plant contributes to is the nitrogen cycle. The plant absorbs the nitrogen from the soil, and then when we eat the plants, we absorb the nitrogen from the plant. Then when the plant exits our body, via our egesta,  the nitrogen, at some point, goes back into the ground to be used by plants again.
