One of the advantages of kelp forests is their ability to remove excess nitrogen and phosphorus compounds from coastal waters.What is the most likely source of excess nutrients?A. Sea ice melting, which releases trapped particles.B. Rain falling on farmland that then carries nutrients into waterways.C. The byproduct from organisms as they convert carbon dioxide and water to create energy.D. Water evaporating from the surface of the ocean increases the amount of nitrogen and phosphorous compounds in the water.

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.

What are the two main sources of nutrient inputs that contribute to eutrophication?a.Industrial waste and sewage dischargeb.Urban runoff and groundwater seepagec.Atmospheric deposition and industrial wasted.Agricultural runoff and sewage discharge

In which of the following do forests not play a significant role ?(1) Soil formation(2) Water conservation(3) Regeneration of carbon dioxide(4) Moderation of

Why are phytoplankton a key part of the marine ecosystem?Multiple choice question.They provide the needed salts to form saltwater.They form the base of the marine food web.They remove the 18O isotope from seawater allowing marine animals to flourish.They shield deep water organisms from harmful UV radiation.
