The plant takes in carbon dioxide from the human and water from its roots. Chlorophyll captures light from the sun from its leaves
The plant goes through photosynthesis leaving products, oxygen, and glucose. The plant keeps the glucose for food and the oxygen going to be in the air. The huma needs oxygen and it takes in the oxygen from the plant.
The human then exhales carbon dioxide. And the plant can keep taking in the carbon dioxide and make food by using photosynthesis if there are enough light, water, and
