Question

Make a poster to show that how dose photosynthesis maintain balance between oxygen and carbon dioxide in the atmosphere?

Answer 1

Answer:

The balance of carbon dioxide and oxygen in atmosphere is mainly maintained by the oxygen released and carbon dioxide consumed during photosynthesis by plants. It is also regulated by the carbon dioxide released by animals during respiration. Thus, the correct answer is 'Photosynthesis.During photosynthesis, carbon dioxide is fixed to form carbohydrate by the dark reaction. The water molecules are broken down during the light reaction and release oxygen. Thus, the two process helps to maintain the balance of oxygen and carbon dioxide in the atmosphere.

Answer 2

Humans release carbon dioxide (CO2) into the atmosphere through cellular respiration. This CO2 is used by plants during photosynthesis. During photosynthesis, plants release oxygen (O2) into the atmosphere. The oxygen is used by animals in order to carry out cellular respiration. And in this way, the cycle continues. Animals create CO2 and plants consume it.

• The balance of oxygen and carbon dioxide is maintained by plants, animals, and humans. Green plants use up carbon dioxide during photosynthesis and release oxygen as a product.

• Whereas, animals and humans use up oxygen during respiration and release carbon dioxide as a by-product. This maintains the overall balance of oxygen and carbon dioxide.
