Why are photosynthesis and cellular respiration considered complementary processes?

Photosynthesis uses energy to make glucose, glycolysis uses glucose to make energy

Explanation:

The simplified equations of photosynthesis and glycolysis are as follows:

Photosynthesis:

carbon dioxide + water + (energy) → glucose + oxygen

Glycolysis:

glucose → pyruvic acid + energy

Photosynthesis uses carbon dioxide, water, and light energy from the sun to generate glucose, which is used as a source of energy for cellular processes.

Glycolysis is the first stage of cellular respiration, which uses glucose to generate energy in the form of ATP.
