Body temperature is the measurement of the heat in an animal`s body. The body of an animal generates heat by burning food. But the animal also loses heat to its environment. Birds and mammals are warm-blooded animals. Their body temperature almost always stays constant. The temperature of their environment does not affect it. The body of warm-blooded animals balances the amount of heat it exchanges with the environment with the amount it produces by burning food. Nearly all other animals are cold-blooded animals. Their body cannot balance this exchange so accurately. As a result, their body temperature changes with temperature of their environment.
