Why is the 10% rule important in understanding energy flow in ecosystems?

• It shows that only 10% of energy is lost at each trophic level

• It suggests that 90% of energy is transferred to the next trophic level

• It explains why energy increases as it moves up trophic levels

• It indicates that only about 10% of energy is passed on to the next trophic level
