A snake is a threat to a mouse for one reason. The one reason why a snake is a treat to a mouse is because that is what snakes eat.
The snake is the predator and the mouse is the prey =] I think that was what you was looking for...
Rattlesnakes are pit vipers and have pits on either side of their head that can detect the warm body of a mouse even when it is dark and the snake cannot actually see the animal.
I belive that is is the primary consumer.
a milk snake
A rat could eat a snake.
I would say food chain.
Eating a frozen mouse can be bad for a snake. The extreme cold can hurt the snake, as it is cold blooded. And because the limbs are not flexible, the snake can be hurt internally.
Optical mouse: Most desktop computer users today have some type of optical mouse, which uses devices that emit and sense light to detect the mouse's movement.
I don't get your question but if you mean if you buy a mouse and feed it to a snake how long will it live then the answer is a couple minutes because the snake will soon sneak up on it and swallow it whole.
