Organisms that are harvested from aquatic systems for food are considered less energy efficient than crops. Why is this true?

• Crops capture directly from the sun, since they are primary producers

• Fish are from less trophic levels so they have a larger energy storage

• Crops are less energy efficient since they perform photosynthesis

• Aquatic organisms are more energy efficient since they perform respiration
