Low body temperature during the winter slows down the need for nutrition. Most of the body's cellular reactions slow down as well. Many animals hibernate which puts their body temperature so low that they must sleep.
ectothermic animals, like frogs, who can't control their internal body temperature
Their body temperature is controlled by their environment. Mammals are endothermic. Meaning that they control their own body temperature.
Cold-blooded animals may change body temperature when the outside temperature changes. This is because they are unable to regulate their body temperature.
Cold blooded animals cannot regulate their own body temperature. Therefore, it changes with their environment.
The body temperature of cold blooded animals changes with the ambient temperature, while warm blooded animals regulate their temperature internally.
No, warm-blooded animals have a built-in heat source that maintains a relatively constant body temperature independent of the environmental temperature.
When taking a cold shower in winter!
Endothermic animals maintain constant body temperature in a number of ways. One way is to lay out in the sun.
All animals use the environment to control their temperature
Warm-blooded animals.
Warm blooded animals all have some ability to regulate their body temperature. Depending on the surrounding temperature, at some point the body temperature will be the same as the plant temperature. But when the surrounding temperature changes, the plant's temperature will change with it, while warm blooded animals will stay at the same temperature.
Animals that do not control their body temperature but rather let the environmental temperature control it are called cold-blooded or the technical term is ectotherm.
