Question

    If the Sun releases 1000 J of energy, then plants take

    only 100 J of energy from sunlight, how much energy would a human obtain by eating the plant following the 10% law?
    A 10 J Correct Answer Incorrect Answer
    B 1 J Correct Answer Incorrect Answer
    C 0.1 J Correct Answer Incorrect Answer
    D 100 J Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    According to the 10% law, only about 10% of the energy is transferred from one trophic level to the next. In this scenario, plants take 100 J of energy from the initial 1000 J of energy released by the Sun. If a human eats the plant, they would obtain 10 J of energy (10% of 100 J), following the 10% law.
