1. This week, we noticed a lot of new things about our plants. It has grown a little bit but it didn't grow as much as we had hoped. Compared to the class, our plant is probably the smallest one. Also, our plant has many holes so small bugs, animals or organisms have been eating it.
2. Our plants participate in the movement of water in the biosphere because our plants need water to grow. Water is one the of the main sources plants need in order to grow and survive. Our plants' roles in the water cycle relate to the changes observed in our plants because they haven't grown that much due to lack of water supply. Last week, our plants grew because it had rained for a couple of days.
3. Our plants participate in the movement of carbon in the biosphere because our plants need sunlight. Like water, sunlight is another main source all plants need to grow. Our plants' roles in the carbon cycle relate to the changes observed in our plants because they haven't grown due to lack of sunlight. Since the weather has been cold and cloudy, the sun hasn't been able to come out.
4. Our plants participate in the movement of carbon in the biosphere because our plants also need nitrogen to grow. Nitrogen is changed by bacteria and ammonium into nitrates and then absorbed by plants. Our plants' roles in the nitrogen cycle relate to the changes observed in our plants because they haven't grown that much due to lack of producing and consuming nitrates correctly.
