Answer:
During the process of photosynthesis, carbon dioxide from the air, and water from the soil is converted into oxygen and glucose. Glucose is a sugar that can be used by the plant for respiration or converted into insoluble starch for storage. Oxygen is a by-product of photosynthesis. Humans and animals need photosynthesis in order to have enough oxygen in the air to survive on. In turn, plants need animals and humans to supply them with carbon dioxide. When we breathe in, our lungs take the oxygen out of our breath, the resulting product, when we breath out, in carbon dioxide.
