8.3721 kcalm2yr
The energy flow in an ecosystem follows the 10% rule, where only 10% of energy is passed from one trophic level to the next. Therefore, the apex predator, in this case the hawk, would only receive 10% of the energy that the fox receives, which is 10% of the energy the rabbits receive, which is 10% of the energy the grass produces.
So, 10% of 83,721 kcalm2yr is 8,372.1 kcalm2yr.
In 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. If the grass produces 83,721 kcalm2yr
of energy, how much energy will the apex predator receive?(1 point)
