Question

Using the rule of 10 percent in energy transfer, record the species names for each trophic level and the amount of energy available at that level if your producer level had 3,500,000 kilocalories of energy/area.

Answer 1

To not make it very complicated we can take only three species that will include producer, consumer of the producer, and a predator. We can take the grass, deer, and cougar.

The grass is the producer, and it is the one that has 3,500,000 kilocalories of energy/area. The deer eats the grass, thus gets energy from it, but only 10%, thus the deer will get 350,000 kilcalories of energy/area. The cougar is a predator, and it hunts the deer. When the cougar kills a deer and consumes it, the cougar will get 10% of the energy that the deer got, thus the cougar will get 35,000 kilocalories of energy/area.
