Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
When fertilizers run off farmland into streams and ponds, the nitrogen content of the water increases. This can lead to rapid growth of algae in a process called eutrophication. How can this process affect other organisms in the water?
A
Oxygen is used up as algae is decomposed, reducing the amount available to other organisms.
B
The water becomes better able to support aerobic organisms.
C
The algae provide food for fishes and other organisms, leading to decreased algae populations.
D
The extra nitrogen provides additional food for the other organisms, increasing their population.
Explanation: 

Detailed explanation-1: -Eutrophication may be defined as the inorganic nutrient enrichment of natural waters, leading to an increased production of algae and macrophytes.

Detailed explanation-2: -WHAT HAPPENS WHEN THERE ARE EXCESSIVE NUTRIENTS? Eutrophication is a natural process that results from accumulation of nutrients in lakes or other bodies of water. Algae that feed on nutrients grow into unsightly scum on the water surface, decreasing recreational value and clogging water-intake pipes.

Detailed explanation-3: -Answer: When fertilizer is added to the freshwater pond then, it will cause Eutrophication. Explanation: When a lake obtains nutrients and sediments from its surroundings, a process known as eutrophication takes place that causes the lake to age.
