Trophic level transfer efficiency is related to population turnover rate in agricultural pests. There are 15g/m2 of locust (herbivorous insect) per 1000g/m2 of wheat (primary producer) and 4g/m2 of cutworms (herbivorous insect) per 200g/m2 of corn (primary producer). __________ have the largest population turnover rate and __________ have the biggest impact on crops.
