Question

can you tell how the plants dependent upon air and water and how they affect the two in return

Answer 1

plants depend upon air for photosynthesis and give up the oxygen for breathing but during night they release carbon dioxide

Answer 2

The net effect depends on the day time and the light intensity.

Photosynthesis doesn’t occur at dark. When there is no photosynthesis, there is a net uptake of oxygen and a net release of carbon dioxide.

If there is enough light during the day, then:

• The rate of photosynthesis is greater than that of the the rate of respiration.

• There is a net uptake of carbon dioxide and a net release of oxygen.
