Answer:
Explanation: Aquatic plants get severely affected due to water pollution. Due to plethora of moss in the polluted water of the rivers, the sun light fails to reach to the depths of the river which affects the growth of aquatic plants in the lack of photosynthesis. In the polluted water of the rivers, some aquatic weed as aquatic ferns and water hyacinth start increasing. Similarly, the sewage water getting mixed into the water of the rivers, helps in the increase of fungus, algae, bacteria, etc which start to erupt faster. Increasing pollution in the sea and oceanic areas has become a threat. ... Fish and other aquatic organisms start dying due to lack of oxygen in the polluted water. Hydrocarbons in the oil spread on the surface of the oceans due to which marine and aquatic organisms do not get the oxygen and they die consequently.
