Biogeochemical Cycles and our Plants
The changes in our plants that I have seen this week were that each of them grew 1-2 inches and are starting to sprout leaves. They are about 7 inches tall and have small green leaves that grow out from the sides of the plant.
Our plants have participated in the water cycle by soaking up rainwater and using it as nutrients to grow. The plants also release water into the soil which gives other organism nutrients. The plants roles in the water cycle relate to my observations for my plants this week because they grew a lot from all the rain we had.
Our plants participate in the movements of carbon in the biosphere by using a process called photosynthesis. During photosynthesis, a plant takes carbon out of the atmosphere and combines it with water to create energy for itself. Our plants role in the carbon cycle related to the changes we observed this week because our plants had large green leaves from photosynthesis.
Our plants participate in the movement of nitrogen in the atmosphere by taking nitrogen out of the air and use it in chlorophyll, making it an essential part of photosynthesis. Our plants role in the nitrogen cycle related to the changes we observed in our plant this week because it made the leaves green from the chlorophyll it made with the nitrogen.
