Why is sunlight important for photosynthesis?

• Sunlight provides the water needed for photosynthesis to occur.

• Sunlight provides the energy needed for photosynthesis to occur.

• Sunlight helps to regulate the temperature for photosynthesis to occur.

• Sunlight provides the carbon dioxide needed for photosynthesis to occur.

How does water reach the leaves for photosynthesis?

• Through xylem vessels

• Through the air

• Through the roots

• Through phloem vessels

Explain the relationship between photosynthesis and the food chain.

• Photosynthesis only benefits plants and not the food chain.

• Photosynthesis provides food for the food chain.

• The food chain provides energy for photosynthesis.

• Photosynthesis has no relationship to the food chain.
