Question

Which observation supports the rule that only 10% of energy is transferred from one trophic level to the next?(1 point)

There are fewer organisms at the top of the food chain because there is less energy available for life processes.

Not all organisms at the lower trophic levels will be eaten and die.

Dead organisms and waste are broken down by decomposers and are recycled through the ecosystem.

10% of organisms are fully consumed while others contain some molecules that cannot be digested.

Answer 1

"There are fewer organisms at the top of the food chain because there is less energy available for life processes."

This observation directly reflects the 10% energy-transfer rule: much less energy remains at higher trophic levels, so fewer organisms can be supported.
