*
1 point
It increases by 10% at each level
It remains constant
It decreases at 10% at each level
It is completely lost

Answer 1

In a food chain, as energy moves from one trophic level to the next, it decreases at approximately 10% at each level. This is often referred to as the "10% Rule," where only about 10% of the energy from one trophic level is transferred to the next level, while the rest is lost primarily through metabolic processes as heat.

So, the correct answer is: **It decreases at 10% at each level.**
