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? Group of answer choicesThe extra nitrogen provides additional food for the other organisms, increasing their population.The water becomes better able to support aerobic organisms.Oxygen is used up as algae is decomposed, reducing the amount available to other organisms.The algae provide food for fishes and other organisms, leading to decreased algae populations.

The process by which nutrients trigger the rapid growth of algae, ultimately leading to O2-depleted water, is calledMultiple choice question.the greenhouse effect.eutrophicationbiomagnification.desalinization.

Eutrophication, part of the natural ageing process for bodies of water such as ponds or lakes, occurs due to a build-up of nitrates and phosphates over time. These compounds, often found in fertilisers, are plant nutrients that stimulate the growth of plants and algae in the water. As the amount of plant matter in the pond increases, more plants start to die off. Bacteria that decompose the dead plants also consume the oxygen in the water, so fish and other water animals soon die for lack of oxygen. The pond eventually becomes choked with plant matter and grows shallower. Ultimately, as shrubs grow where water once was, the pond dies.Which organisational structure does this text primarily use?

What is a consequence of eutrophication on aquatic ecosystems?*1 pointIncreased biodiversity due to nutrient enrichment.Harmful algal blooms and oxygen depletion.Enhanced water quality and clarity.Decreased algae growth and oxygen depletion.

Eutrophication is the growth of Algal bloom induced bya) Nutrient depletion in freshwater bodiesb) Nutrient enrichment in freshwater bodiesc) Heavy metal accumulation in freshwater bodiesd)Toxic chemical accumulation in freshwater bodies
