Question

Why are birds and mammals warm blooded while amphibians are cold blooded?

Answer 1

Answer:

Warm-Blooded vs. Cold-Blooded. Warm-blooded creatures, like mammals and birds, try to keep the inside of their bodies at a constant temperature. They do this by generating their own heat when they are in a cooler environment, and by cooling themselves when they are in a hotter environment.

Cold-blooded creatures take on the temperature of their surroundings. They are hot when their environment is hot and cold when their environment is cold. In hot environments, cold-blooded animals can have blood that is much warmer than warm-blooded animals. Cold-blooded animals are much more active in warm environments and are very sluggish in cold environments. This is because their muscle activity depends on chemical reactions which run quickly when it is hot and slowly when it is cold. A cold-blooded animal can convert much more of its food into body mass compared with a warm-blooded animal.

Answer 2

Here is your answer dude,

Birds and mammals are cold blooded because they have four chambered heart that separates oxygen rich blood from that of CO2 rich blood this ensures sufficient supply of oxygen to the body and produce energy.They use this energy to maintain their body temperature.

Whereas amphibians have three chambered heart that allows mixing of oxygen and carbon dioxide rich blood hence their body temperature is dependent on the surrounding because they do not have sufficient supply of oxygen.

This is the reason why birds and mammals are warm blooded whereas amphibians are cold blooded.
