In a food chain with four trophic levels, what would be the energy in the top trophic level if the energy contained in the primary producer level is 40,000 kcal/m²/yr? Assume a trophic level transfer efficiency of 10%. A)4,000 kcal/m²/yr B)400 kcal/m²/yr C)40 kcal/m²/yr D)4 kcal/m²/yr

The energy decreases by 90% at each trophic level due to the 10% transfer efficiency. Starting with 40,000 kcal/m²/yr, the energy at each level would be: 1st level (producers) = 40,000 kcal, 2nd level = 4,000 kcal, 3rd level = 400 kcal, and 4th level (top) = 40 kcal.
