Phytoplankton use sunlight to gain energy through photosynthesis. As a result of the Law of Conservation of Energy, phytoplankton cannot gain more energy than it consumes. A closed system consisting of an aquarium, phytoplankton, and sunlight is set up. Which of the following methods would best demonstrate the Law of Conservation of Energy? (3 points)

A. Measure the mass and temperature of the water. Then cover the aquarium to block the sunlight and measure the mass of the phytoplankton.
B. Change the closed system to isolated, so that energy can move out of it. Then measure the amount of energy that leaves.
C. Measure the mass of the phytoplankton before and after photosynthesis. Add the mass of the water.
D. Measure the amount of energy in the phytoplankton 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.

D

This will determine how much of the sunlight has been captured and converted from light energy to chemical energy. Photosynthesis is the main process that does this transformation of energy in photosynthetic organisms like plants and phytoplankton.

Explanation:

However the process of photosynthesis is very inefficient. Less than 10% of the sunlight will be captured and transformed by the plant. Therefore, in the experiment, there should be a great difference between the energy of sunlight measured and the amount of energy in the phytoplankton after exposure to the sunlight. However, nor energy is created nor destroyed in the process hence observing the Law of Conservation of thermodynamics.
