Question

What happens to energy as you move up food chain

Answer 1

Only 10% of the energy moves up the chain. So it decreases.

Answer 2

As you move up to the food chain, the energy will decrease. This explains  that the more the consumers, the lesser the energy that the last consumer will get from the sunlight. This is because each energy will decrease as it passes by the consumers because each consumers takes a portion of the full energy from the sun.
