Explanation:
The correct sequence in which these zones occur progressively downstream in a polluted river is option 'B': 4, 2, 3, 1.
Zone of degradation (4):
The zone of degradation is the first zone that occurs downstream in a polluted river. This zone is characterized by high levels of pollution and degradation. It is the area where the river receives the highest concentration of pollutants, such as industrial waste, agricultural runoff, and sewage. As a result, the water quality in this zone is severely degraded, and the ecosystem is significantly impacted.
Zone of active decomposition (2):
The zone of active decomposition occurs after the zone of degradation. In this zone, the high levels of pollution present in the water lead to increased microbial activity. Bacteria and other decomposers break down the organic matter present in the water, resulting in active decomposition. This process consumes oxygen, leading to oxygen depletion in the water.
Zone of recovery (3):
The zone of recovery comes after the zone of active decomposition. In this zone, the water quality starts to improve as the pollution levels decrease. The decomposed organic matter is gradually removed from the water, and the oxygen levels begin to increase. The ecosystem in this zone starts to recover, and aquatic life becomes more abundant.
Zone of clear water (1):
The zone of clear water is the last zone that occurs downstream in a polluted river. In this zone, the pollution levels have significantly decreased, and the water quality has improved. The water appears clear, and the ecosystem is relatively healthy. Aquatic life is able to thrive in this zone, and the river returns to a more natural state.
Therefore, the correct sequence of zones progressively downstream in a polluted river is: 4, 2, 3, 1.
The correct sequence in which these zones occur progressively downstream in a polluted river is option 'B': 4, 2, 3, 1.
Zone of degradation (4):
The zone of degradation is the first zone that occurs downstream in a polluted river. This zone is characterized by high levels of pollution and degradation. It is the area where the river receives the highest concentration of pollutants, such as industrial waste, agricultural runoff, and sewage. As a result, the water quality in this zone is severely degraded, and the ecosystem is significantly impacted.
Zone of active decomposition (2):
The zone of active decomposition occurs after the zone of degradation. In this zone, the high levels of pollution present in the water lead to increased microbial activity. Bacteria and other decomposers break down the organic matter present in the water, resulting in active decomposition. This process consumes oxygen, leading to oxygen depletion in the water.
Zone of recovery (3):
The zone of recovery comes after the zone of active decomposition. In this zone, the water quality starts to improve as the pollution levels decrease. The decomposed organic matter is gradually removed from the water, and the oxygen levels begin to increase. The ecosystem in this zone starts to recover, and aquatic life becomes more abundant.
Zone of clear water (1):
The zone of clear water is the last zone that occurs downstream in a polluted river. In this zone, the pollution levels have significantly decreased, and the water quality has improved. The water appears clear, and the ecosystem is relatively healthy. Aquatic life is able to thrive in this zone, and the river returns to a more natural state.
Therefore, the correct sequence of zones progressively downstream in a polluted river is: 4, 2, 3, 1.
