Question

what do plants do with the carbon they receive? they turn it into water they dont need carbon they keep it forever they turn it into food by photosynthesis

Explanation:

To answer this, we recall plant biology: Photosynthesis is the process where plants use carbon dioxide (containing carbon), along with water and sunlight, to produce glucose (food) and oxygen. Let's analyze each option:

• "They turn it into water": Carbon can't be turned into water (water is H₂O, no carbon in the same form). Eliminate.
• "They don't need carbon": Plants need carbon (from CO₂) for photosynthesis. Eliminate.
• "They keep it forever": Plants use carbon for growth, respiration, etc., and it cycles, not kept forever. Eliminate.
• "They turn it into food by photosynthesis": Matches the photosynthesis process where carbon from CO₂ is used to make glucose (food).

Answer:

The correct option is "They turn it into food by photosynthesis" (the fourth option among the choices).
