One of the signs that make it possible to distinguish living from non-living.

The main feature that makes it possible to distinguish living matter from non-living matter is the processes of metabolism and energy conversion that take place in the body. Metabolism is a complex process that makes life possible in the body. It consists of two opposite processes of anabolism and catabolism. In living objects, many different biochemical processes take place, for example, food is processed to form energy, which is spent on vital activity. Such processes do not occur in non-living objects.
