Ectotherms
Definition
Ectotherms are organisms that rely on external sources of body heat.
Analogy
Think of ectotherms like a solar-powered calculator. They need an external source (the sun) to function properly, just like ectotherms need the environment's temperature to regulate their body heat.
Related terms
Endotherm: An organism that generates its own body heat internally, much like a battery-powered device.
Poikilotherm: An organism whose internal temperature varies considerably. It's like a chameleon changing colors based on its surroundings.
Thermoregulation: The process by which animals maintain an optimal body temperature, similar to how you would adjust your home's thermostat to keep it comfortable.
