1. Photosynthesis: This is an endothermic reaction that occurs in plants. They absorb sunlight (heat energy) and convert carbon dioxide and water into glucose and oxygen.

2. Dissolving a salt: When salt is dissolved in water, it absorbs heat from the surroundings, making it an endothermic reaction. The water becomes cooler as the salt dissolves.
