How do animals store long term energy? why?

They store it as fat

Explanation:

proteins and carbs can both be converted into fat inside the body. When an animal eats more food than needed, the extra gets converted into fat and stored in adipose cells. During times with low amounts of food, the body can convert the fat into usable energy.

the cells uses some of the atoms of the glucose molecules to atp molecules. the atoms of the glucose molecules will then be converted into energy which will be eventually stored in atp. the energy produced which are stored in atp are coming from the glucose’s chemical bonds.

maybe because its impossible for balloons to lift a whole entire house.
