Correct Answer: Zone of degradation
Solution : The correct option is zone of degradation.
The lack of fish in a river might be an indication of zone of degradation within that ecosystem. Because fish are sensitive to changes in water quality and habitat conditions, their absence frequently indicates issues such as pollution, habitat loss, low oxygen levels, sedimentation, invasive species, and the effects of climate change. Monitoring fish populations and their distribution is critical for assessing a river's health and guiding conservation efforts to restore and preserve the waterway's natural balance.
