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.

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.

step 1 ammonium can be absorbed by plants, but some is converted into nitrates which are better for plants to absorb. this is called nitrification. 2. step 2 the deer eats the plants and uses the nitrogen-containing proteins for cell growth. 3. step 3 bacteria in the soil conduct nitrogen fixation to convert nitrogen gas from the atmosphere into ammonium. 4. step 4 some of the nitrates are absorbed back into plants, but denitrification breaks down the nitrates into nitrogen gas released back into the atmosphere. 5. step 5 nitrogen is found in the urine, which gets broken down into ammonium through the process of ammonification. 6. step 6 plants absorb the ammonium and begin assimilation, the process to add the nitrogen to protein.

equal distribution i think.
