In energy transfer between trophic levels, an average of only about 10% of energy (or carbon) is transferred between trophic levels. What are the factors that affect: A.) Exploitation efficiency (why isn't everything eaten?) B.) Assimilation efficiency (why isn't everything that is ingested assimilated?) C.) Production efficiency (what happens to all that assimilated energy?) Please explain how and why. I need help!!
