Knowing the 10 percent rule (correct ecological pyramid: no more than 10% of the energy comes from each previous trophic level to the next), calculate how many tons will be needed for phytoplankton to grow one whale weighing 150 tons? (food chain: phytoplankton → zooplankton → whale)

150,000 10 10 = 15,000,000 kg = 15,000 tons.
