If the producer has 500,000 kcal of stored energy, how much would reach the top predator?

• 500 kcal would reach the top predator (10% of 500,000 kcal for each level: producer → herbivore → carnivore → top predator).

• 50,000 kcal would reach the top predator (10% of 500,000 kcal for each level: producer → herbivore → carnivore → top predator).
