That depends on whether the vertebrate is warm or cold blooded. Animals such as fish and amphibians have to be able to survive with a body temperature similar to their surroundings, because they are cold blooded and they can't leave the water long enough to really warm up. Reptiles are cold blooded, but they can warm up by basking in sunlight. Mammals and birds are warm bloded, so they generate heat internally from the energy they get from food.
Hair and fur
Mammals will shiver or posses what is called 'brown fat' that continuously produces heat.
Mammals are covered in hair. They are endothermic ( produce their own body heat) They produce milk to nurse their young.
They are mammals, as are all bats, and most mammals have body fur for heat control and skin-protection.
because mammals can produse there own body heat.
Rats can not regulate their body heat. Most mammals can regulate their body heat when their blood is high enough.
Mammals belong to the phylum Chordata and are endothermic, meaning they can produce and regulate their own body heat.
Yes. All mammals are endothermic, able to regulate their own body heat. The term 'endothermic' is the correct name for an animal that is warm-blooded.
The more fat that there is on an animal the more heat it will be able to store, because the fat and blubber trap in heat.
Yes. A chicken is a bird; like mammals, birds are endotherms and generate their own body heat.
In the same way that all mammals maintain their body heat - by burning calories digested from their food.
