What kind of energy is the sun?

• renewable

• non renewable

Look at the picture above. Formulate a cause and effect prediction that can be used to test the assumptions in the model of photosynthesis.

• limiting carbon dioxide will limit sugar production of the plant

• limiting sunlight, water, or carbon dioxide will limit sugar production of the plant

• limiting sunlight will limit sugar production of the plant

• limiting water will limit sugar production of the plant
