Final answer:

Exothermic reactions release energy, while endothermic reactions absorb energy.


Explanation:

An exothermic reaction is one that releases energy into the environment. In contrast, an endothermic reaction absorbs energy from the environment.

For example, the combustion of methane gas in kitchen burners is an exothermic reaction, releasing energy. On the other hand, photosynthesis is an endothermic reaction, absorbing sunlight for energy.
