Hi there

Please find your answer below:

If 20 J of energy is trapped by the plants (producers), then the energy available to the subsequent trophic levels can be estimated as follows:

1. First Trophic Level (Plants):

   • Energy trapped by plants = 20 J

2. Second Trophic Level (Mice):

   • Approximately 90% of energy is lost, so the energy available to mice = 0.1 * 20 J = 2 J

3. Third Trophic Level (Snake):

   • Again, approximately 90% of energy is lost, so the energy available to the snake = 0.1 * 2 J = 0.2 J

4. Fourth Trophic Level (Peacock):

   • Once more, approximately 90% of energy is lost, so the energy available to the peacock = 0.1 * 0.2 J = 0.02 J

Therefore, if 20 J of energy is trapped by the plants, the estimated energy available to the peacock as food in the subsequent trophic levels is around 0.02 J. This illustrates the significant energy loss that occurs as you move up the food chain.

 

CORRECT ANSWER IS (B)
