1. Consider a population of beetles in a pine forest, where both the beetles and the pine trees are in steady state. The beetles consume 2% of the net primary productivity of the trees and have an incorporation efficiency of 15% (that is, 15% of the biomass they eat is incorporated into beetle biomass). a. If the average residence time (ignoring respiratory, metabolic, and excretory pathways) of carbon in the beetle population (i.e., average beetle lifespan) is 1 month and that in pine trees is 25 years, what is the ratio of the biomass of beetles to that of pine trees? (10 pts.) b. Given your answer above, how many beetles will there be on an individual mature pine tree? (state your assumptions) (5 pts.) 1.
