Biogeochemical Cycles and our Plants

Our romanesco, has not grown that much bigger, and there are a lot of bug eaten holes in them. Plants play a role in the nitrogen cycle, they absorb nitrogen from the soil. So when plants are eaten the creature that eats it it drops droppings with nitrogen that returns to the soil. Also when the plant dies the nitrogen returns to the soil then too. Plants need carbon too, so when a air breathing creature breaths out carbon. A plant breathes it in and expels out oxygen. Plants also play a role in the water cycle, when it rains plants pull up water through their roots, then some of the the water is evaporated out through the leaves. The water that is evaporated floats up into the atmosphere, until it rains.
