This is a diagram that showing the relationship in nature. There is a life balance between each items on earth. The plants get energy from sun and produce oxygen and glucose. This process called photosynthesis. The oxygen produce for animal and human. Human and animals need air. They will produce carbon dioxide after they get the air into their body. This is called respiration. After that, the plants will absorb the carbon dioxide and produce the oxygen again. This is how the earth work. It have a perfect organization in each relationship in the nature.
