Transcript of The Difference Between Endothermic and Ectothermic

Endothermic
Endothermic animals must eat much more often than ectothermic animals since it takes energy to maintain a constant body temperature.
Ectothermic
Some animals must bask in the sun( for examples snakes or lizards) or move to a warmer area( for example some fish) before they can move about to hunt for food.
If the temperature gets too hot, ectothermic animals will need to find a cooler temperature or burrow in the ground to keep its body cool.
Endothermic
When the outside temperature is too hot, an endothermic animal can cool off.
Examples: Sweating, Panting, Changing position and changing location.
Ectothermic
If an animal is cold-blooded, they take on the temperature of their surroundings so they don`t have to use food energy to keep warm.
This means they dont have to eat often.
The Difference Between Endothermic and Ectothermic Animals

Ectothermic
Cold-blooded
Includes fish,amphibians,and reptiles.
Having internal body temperature that changes with the temperature of the environment.
Ectothermic
They must gain heat to perform internal activities( for example digestion)
If the environment is cold, ectothermic animals become slow moving and sluggish.
Endothermic
Warm-blooded animals
Includes birds and mammals
Maintain a nearly constant internal temperature
Do not change with the temperature or the envioronment.
Endothermic
Sweating and panting generates heat loss through evaporating water.
Changing position and location allow the animal to find a cooler environment in the shade or shelter.
