Most animals can survive without food for a longer time than they survive without water. Why is water so important to animals? Why can an animal survive without food for longer?

It depends on the climate they are in and what kind of animal is like if the climate is really hot so the animals need more water than food.

Water is important to animals as water is required for many uses such as tissue repair or cell division. However many animals have a food storage. So if u go food free for some time, you will probably still survive as the body will use up the food storage of glycogen or fats.
