What is the 90/10 Rule in ecology?

• 10% of energy is passed to the next trophic level, and 90% is lost to processes like respiration and heat.

• 90% of energy is passed to the next trophic level, and 10% is lost to processes like respiration and heat.

• 50% of energy is passed to the next trophic level, and 50% is lost to processes like respiration and heat.

• 100% of energy is passed to the next trophic level with no loss.
