As a result of the law of conservation of energy, phytoplankton cannot produce more energy than it absorbs from the sun. which method, using phytoplankton grown in an aquarium, would best test this hypothesis?

measure the amount of energy in the aquarium and the amount of light entering the aquarium. then measure the amount of energy in the phytoplankton after exposure to the light and determine the difference.

measure the amount of energy in the phytoplankton, the aquarium in the dark, and the amount of light entering the aquarium. then measure the amount of energy in the phytoplankton and the aquarium after exposure to the light and determine the difference.
