In one square meter of open ocean, phytoplankton can generate 1,600,000 Calories of chemical “food” energy per year. Assuming that there is a 90% “loss” of usable chemical energy during transfers form one trophic level to the next, calculate the energy available at each trophic level for each of five trophic levels.

Effect of rotenone and antimycin a on electron transfer rotenone, a toxic natural product from plants, strongly inhibits nadh dehydrogenase of insect and fish mitochondria. antimycin a, a toxic antibiotic, strongly inhibits the oxidation of ubiquinol. (a) explain why rotenone ingestion is lethal to some insect and fish species. (b) explain why antimycin a is a poison. (c) given that rotenone and antimycin a are equally effective in blocking their respective sites in the electron-transfer chain, which would be a more potent poison? explain.
