Detailed explanation-1: -Eutrophication is the process in which the water body becomes overly enriched with nutrients, leading to an increase in the production of algae and macrophytes. It deteriorates the water quality and depletes the dissolved oxygen of water bodies.
Detailed explanation-2: -Excessive amounts of nutrients can lead to more serious problems such as low levels of oxygen dissolved in the water. Severe algal growth blocks light that is needed for plants, such as seagrasses, to grow. When the algae and seagrass die, they decay.
Detailed explanation-3: -Assertion :Presence of large amounts of nutrients in water body causes excessive growth of planktonic algae. Reason: It is due to biomagnification.
Detailed explanation-4: -Harmful algal blooms, dead zones, and fish kills are the results of a process called eutrophication-which occurs when the environment becomes enriched with nutrients, increasing the amount of plant and algae growth to estuaries and coastal waters.
Detailed explanation-5: -Nutrient pollution damages the environment and harms water quality. Algal blooms consume large amounts of oxygen that fish, shellfish and other aquatic organisms need to survive. They make water cloudy, reduce the ability of aquatic life to find food, and clog fish gills.
