I think there are many circles in the environment. One of them is how rain falls from the clouds and becomes a river and flows down mountains. It then flows into the ocean. From there, it evaporates into a cloud again and the cycle continues. Another circle that exists in the environment is the growth of flowers. Flowers bloom from seeds. The seeds grow into leaves and stems and finally blooms into a flower. The flower holds seeds in the middle, an when it wilts, the seeds drop to the ground, and the cycle repeats itself over and over again.
I think the environment is made up of many circles.
