In photosynthesis, carbon dioxide reacts with water to produce glucose and oxygen, and this reaction absorbs energy from sunlight.
- •
Endothermic reactions absorb energy, while exothermic reactions release energy into the surroundings.
- •
The law of conservation of energy states that energy is not created or destroyed, but only transferred from one entity to another.
