Wildlife biologists are attempting to monitor the population size of the insect pest known as the gypsy moth (lymantria dispar) during the summer months. to estimate the total population size of these insects living in a 50 square kilometer forest, biologists have sampled random trees, counting the number of eggs and larvae on each randomly selected tree. which of these factors most directly impacts the accuracy of this estimate? a) the number of trees sampled b) the presence of gypsy moth predators c) the overall health of the gypsy moth population d) the weather conditions at the time of the sampling
