assalam o alaikum everyone I hope you are doing well

In this topic he is discussing how different animals produces there own heat or how do they get heat .

There are two types of animals who can regulate heat and those which cannot.In this topic he is discussing different types of animals related to heat production.They are;

A. Endotherms:
     Which produce heat from metabolism. 
Examples:
     Birds,invertebrates,mammals etc.
B. Ectotherms:
     Which take heat from surrounding.
Examples:
     some fish,Reptiles,amphibians etc.
C. Heterotherms:
     Which cannot regulate heat.
Examples:
     Bats and humming birds etc.

Endotherms:  are the organisms that produce heat from metabolism and does not take heat from surrounding or produce variant degree of heat.
The reactions taking place in the stomach and thus becoming a source of energy and heat for living organisms are called endotherms.

Ectotherms: are the organisms that produces low amount of metabolic heat and take heat from surrounding.The heat can come from the rays of sunlight or the heat produced from industries and factories.Thus these are ectotherms.

Heterotherms: are the organisms that produces variant degree of heat and generally do not regulate heat are called heterotherms.For example like bats when they fly due to muscle activity they become very hot and cannot regulate their body temperature to cool their temperature.So they put saliva or urine on there self this process causes evaporative 
cooling.
