Answer: The detritus food chain is the major pathway of energy flow.
- A Producers are absent
- B Energy is flowing upward through the chain without any loss
- C Biomagnification is occurring
- D The detritus food chain is the major pathway of energy flow
Correct answer: D. The detritus food chain is the major pathway of energy flow
Explanation: In many ecosystems, especially terrestrial ones, most energy moves through the detritus food chain rather than the grazing food chain.
