C
4.6%
Verified step by step guidance1
Identify the relevant data from the table: Net grass production is 8,230 kcal/(m²*yr) and Gross insect production (assimilated) is 520 kcal/(m²*yr).
Understand that trophic efficiency is calculated as the ratio of energy at one trophic level to the energy at the previous trophic level, expressed as a percentage.
Use the formula for trophic efficiency: Trophic Efficiency (%) = (Energy at higher trophic level / Energy at lower trophic level) * 100.
Substitute the values into the formula: Trophic Efficiency (%) = (520 / 8,230) * 100.
Calculate the result to find the trophic efficiency between insects and grass.
