Reptiles can't keep warm all by themselves. They are ectothermic which meens they are cold blooded. That meens that they need the sun or somthing elses heat to keep warm. Whatever their surrounding climates temperature is is what the reptiles temperature is. They will lose energy and may die in the cold.

Lizards are cold blooded because they are reptiles and like other reptiles they go out in the sun to keep warm.
To keep vital organs warm.
Because being warm blooded, they need food to keep themselves warm.
Similarities: 1. Both breath oxygen 2. Both give birth 3. Both have internal organs (heart, lungs, stomach etc.) Diferences: 1.
