And a grassland ecosystem grass is the producer the grass is eaten by rabbits the rabbits are eaten by Foxes and the foxes are eaten by hawks in the grass produces 83,721 KCAL M2 year of energy how much energy will the apex predator receive
The energy transfer efficiency between trophic levels is typically around 10%, meaning that only 10% of the energy from one trophic level is transferred to the next level.
So, if the grass produces 83,721 KCAL/m2/year, the rabbits would receive only 10% of this energy, which is 8,372.1 KCAL/m2/year. The foxes would then receive 10% of this energy, which is 837.21 KCAL/m2/year. Finally, the hawks as the apex predator would receive 10% of the energy from the foxes, which is 83.721 KCAL/m2/year.
Therefore, the hawks would receive 83.721 KCAL/m2/year of energy in the grassland ecosystem.
