Why Is Heat Energy Is Important For The Survival Of Living Things?

Heat energy allows your body and other organisms to move faster due to increased molecular activity, additionally, if your body was 0 degrees Celsius or 32 degrees Fahrenheit your body would shut down. Also, certain temperatures speed up blood coagulation, photosynthesis, metabolic reaction, and so on.

It is due to molecules being able to move around and do the things they do. If you freeze, you stop movement life

It is important because if we don't have heat in our bodies we can die and so would the animals.
