Hi,

While I agree with Gregg that they are separate functions, they overlap and are both related to available heat choices. More available heat speeds up both processes. Snakes can digest more and larger food items when they are given access to higher temps, while still maintaining the cool options (this is important). This effects metabolism by allowing more calories and nutrients to cells that are ready to process them, allowing snakes to grow at the upper end of their genetic potential.
