Answer:
B. Limber pine
Explanation:
Going up the trophic levels, the energy is most concentrated in the lowest level. As it goes up, the amount of energy obtained through the consumption of those below is only 10% of the previous. So producers get the most energy, directly from the sun. (ex. 1000kcal) When the primary consumers eat them, they get only 10% of that energy obtained from the sun (which will be 10% of 1000).
