- 7. Multiple ChoiceThe diagram is intended to show relationships in an ecosystem. What do the arrows represent?The direction of population migrationDifferences in dietary habitsProgressively smaller organismsThe direction of the energy flow
- 8. Multiple ChoiceThe diagram represents different levels of a marine food pyramid. Between which two levels is the greatest amount of energy transferredR and QS and RT and SU and T
- 9. Multiple ChoiceThe diagram represents a model of a food pyramid. Which statement best describes what happens in this food pyramid?More organisms die at higher levels than at lower levels, resulting in less mass at higher levels.Energy is lost to the environment at each level, so less mass can be supported at each higher level.When organisms die at higher levels, their remains sink to lower levels, increasing the mass of lower levels.Organisms decay at each level, and thus less mass can be supported at higher levels
