Question

What do plants absorb from the atmosphere?
*
Oxygen
Nitrogen
Water
Carbon dioxide

Answer 1

Plants primarily absorb carbon dioxide from the atmosphere during the process of photosynthesis. While they do need oxygen for respiration, they do not absorb it directly from the atmosphere in the same way. Nitrogen is absorbed from the soil in the form of nitrates and ammonium, and water is taken up through their roots from the soil. Therefore, the correct answer is carbon dioxide.
