Suppose a forest ecosystem contains plants and deer that eat the plants. gross primary productivity in the ecosystem is 240,000 kcal/m2 /year (we’ll use this unit for all non-percent numbers in this exercise). if the respiration rate of the plants is 75%, what is the net primary productivity of the forest in kcal/m2 /year? suppose that, of the energy contained in plants (the net primary productivity), deer eat 30,000 kcal/m2 /year. what is the conversion efficiency of the deer? suppose that, of that energy eaten by the deer, 24,000 kcal/m2 /year is absorbed by the animals during digestion. what is the assimilation efficiency of the deer? suppose that, of the energy absorbed by the deer, 12,000 kcal/m2 /year is stored in their tissues. what is the production efficiency of the deer? finally, comparing all of the numbers here, what is the efficiency of energy storage into plant tissue from animal tissue?
