Stored as chemical energy in glucose
During a chemical reaction, energy is either absorbed or released. If energy is released, it is usually in the form of heat. If energy is absorbed, the reaction requires an external energy source to proceed.
From the sun
energy
When a light wave is absorbed by an object, the absorbed light energy is converted into heat or other forms of energy within the object.
Light energy that is not absorbed by a material is typically reflected, transmitted, or scattered.
During an endothermic reaction, energy is absorbed from the surroundings, typically in the form of heat. This energy is used to break chemical bonds in the reactants, allowing the reaction to proceed. As a result, the temperature of the surrounding environment may decrease, and the products of the reaction have higher energy than the reactants. Overall, the absorbed energy is stored within the chemical bonds of the products.
The three changes of state during which energy is absorbed is: conduction, convection, & radiation.
Energy is released during freezing.
Energy from the sun that is absorbed by the Earth's surface is reflected back into the atmosphere or absorbed by land and water and transformed into heat.

when a chemical change occurs, chemical bonds are broken up
energy is released
