warm blooded animals create their own body heat, expending extra energy to do so.
cold blood animal rely on the the ambient temperate of surrounds for their body temperature, and expend less energy, but also get sluggish when things are cool to cold.
Warm-blooded animals keep a constant body temperature. This means they can be active at night, and up first on a cold morning. It also means they need a lot more food.
Warm-bloods tend to be more complex. The adaptation occurred separately in birds and mammals. Maybe also dinosaurs, this is disputed.
The curious extinct reptiles with 'sails' on their backs were related to the ancestors of mammals and it is thought this was a primative way to gain heat or lose it. Losing heat is part of it and most mammals sweat.
So-called cold blooded animals can't control their body temperature themselves. They will basically always be ath the same temperature as their surroundings.
If they get cold, they have to move somewhere warmer, or become sluggish.
If they get too warm, they can't sweat or cool themselves down (much), and will rely on moving into shade, or into water, or something like that to cool down.
Because humans are mammals and SOME animals are cold blooded because their reptiles or amphibian's.

animals need warm or cold blood to fit their habitat.
evolution
Say that they are warm blooded.
dinosaurs are the animals which are warm blooded.
Warm blooded
Say that they are warm blooded.
Fish, amphibians and reptiles are cold blooded. Birds and mammals are warm blooded.
Dinosaurs are a group of reptiles, therefore they are cold-blooded.
Warm blooded animals can generate their own heat in a cold enviorment. Cold blooded animals change their temperature if they are in a cold place their body temperature changes cold if they are in a warm place it changes warm. Temperature change
warm blooded animals, or endothermic animals, are animals that keep a constant body temperature. Cold blooded animals, or ectothermic animals, are animals who can't keep a constant bodt temperature, an their body temperature changes with the air around them. I'm sorry if this is not detailed enough
Cold blooded animals do not control their internal body temperature. Warm blooded animals do.
cold blooded
warm blooded because cold blooded are mean animals and there harder to teach
Mammals are not cold blooded.They are warm blooded.
