Why is the energy available at the top layer of the food pyramid only a small percentage of the energy present at the bottom of the pyramid?

As the food chain goes higher, the amount that is received is only 10% because the other 90% is either used up by the lower level organism or is unattainable.

And the food at the bottom keeps you going for longer.
