plants release oxygen when they decompose take in oxygen for photosynthesis.

plants take in oxygen during photosynthesis and absorb carbon dioxide through their leaves and roots.
plants use oxygen to perform photosynthesis and release carbon dioxide as a by-product.

Option B

Explanation:

The plants uses sunlight to convert carbon dioxide and water into more complex carbohydrate known as glucose.

Plants utilize carbon dioxide during photosynthesis. Plants absorb water through roots and leaves.

Plants release oxygen as a by-product which is used by animals and other organism.

The carbohydrates inside the plants is broken down into simpler form and the energy released is used by plants for its cellular processes. This is known as cellular respiration.
