Solution

The correct option is C 405 J
The food chain which involves both wolf and fox is: Vegetation → Rabbit → Fox → Wolf → Tiger According to the 10 percent law, only 10% of energy is passed on to the next trophic level and the rest 90% of energy is lost at each trophic level. The amount of energy stored in plants (vegetation) is 45000 J (45 kJ), which keeps on reducing with each trophic level.

Amount of energy gained when tiger preys on fox = 450 J Amount of energy gained when tiger preys on wolf = 45 J So, the difference between the gained energy by the tiger if it preys on wolf and fox respectively is 450 J – 45 J = 405 J.
