OVERHEADS:

Heat -  energy resulting from random motion of molecules within a substance

Temperature – measure of average kinetic energy of molecules in a substance

Conduction - direct transfer of heat from one substance to another

Convection - transfer of heat by circulation within a fluid

Radiation - heat transfer through waves that release energy when they are absorbed by an object

Poikilotherms - body temperature varies with ambient temperature

Homeotherms - maintain constant body temperature regardless of ambient temperature

Ectotherms - rely on external energy source for thermoregulation - reptiles, amphibians, fish, insects, plants

Endotherms = rely on metabolic heat production for thermoregulation- birds & mammals
