Best answer:

Answer by Alistair Kendrick
No. Different molecules have different quantities of energy per mass. For instance fats are higher in energy per mass than carbohydrates. Therefore an organism that has a high proportion of fat will have more energy per mass than an organism that has a high proportion of carbohydrates. Therefore 2 billion calories of an organism that is high in fat will weigh less than 2 billion calories of an organism that is high in carbohydrates.
