Question

How does the light reaction of photosynthesis affect Earth's supply of oxygen?

о It absorbs oxygen, thus decreasing Earth's oxygen supply.
It releases carbon dioxide and decreases Earth's supply of oxygen.
It releases oxygen and increases Earth's oxygen supply.
It produces water and does not affect Earth's oxygen supply.

Answer 1

The light reaction of photosynthesis releases oxygen and increases Earth's oxygen supply.

Step-by-step explanation:

The light reaction of photosynthesis affects Earth's supply of oxygen by releasing oxygen and increasing Earth's oxygen supply.

During the light reaction, photosynthetic organisms capture light energy and convert it into chemical energy in the form of ATP and NADPH. Water molecules are split, releasing oxygen as a byproduct. This oxygen is then released into the environment, contributing to Earth's oxygen supply. Overall, photosynthesis is essential for maintaining the oxygen balance on our planet.
