Question

1. in photosynthesis, water, carbon dioxide, and light energy react to produce glucose and oxygen. based on the law of conservation of energy, what happened to the light energy in the reaction? select two correct answers. it was neither created nor destroyed. it was converted into chemical energy stored in the sugar. it was destroyed. it was converted into carbonic acid.

Explanation:

• According to the law of conservation of energy, energy is neither created nor destroyed. So the light energy was not destroyed.
• In photosynthesis, light energy is converted into chemical energy which is stored in glucose (a type of sugar). Carbonic acid is not a product related to the conversion of light energy in photosynthesis.

Answer:

• It was neither created nor destroyed.
• It was converted into chemical energy stored in the sugar.
