What Type Of Water Generally Holds The Most Nutrients In The Ocean?

Why is open ocean so low in productivity?

These factors include the availability of essential inorganic nutrients, particularly nitrogen and phosphorus; water temperature; and the turbidity of the water.

Open oceans have relatively low primary productivity because of low levels of the essential nutrients nitrogen and phosphorus..

What is primary productivity in the ocean?

Primary productivity is the rate at which atmospheric or aqueous carbon dioxide is converted by autotrophs (primary producers) to organic material. Primary production via photosynthesis is a key process within the ecosystem, as the producers form the base of the entire food web, both on land and in the oceans.

Can phytoplankton live in warm water?

In fact, phytoplankton in warmer equatorial waters can grow much faster than their cold-water cousins. … Phytoplankton have so far adapted fairly well to local current temperatures, but based on projections of future ocean temperatures, they may not be able to do so quickly enough to changes in their current environment.

How deep ocean actually is?

The ocean is deep. … Officially anything deeper than just 200 metres is considered the “deep sea”, but the average depth of the entire ocean is about 3.5km and the deepest point – the Challenger Deep in the Mariana Trench, in the western Pacific – is a little short of 11km down.

How many dead zones are there?

400 dead zonesA 2008 study found more than 400 dead zones exist worldwide—anywhere excess nutrients travel downstream and into a body of water. (Read about a large dead zone in the Baltic Sea.)

What is the most abundant gas found in ocean water?

Nitrogen gasNitrogen gas (N2) from the atmosphere dissolves into seawater at the ocean surface. Nitrogen gas is the most abundant form of nitrogen in the ocean, but is not useful to most living things.

Why are oceans least productive?

The Brainliest Answer! There is insufficient radiation as sunlight decreases with the increasing depth of the ocean.

Do tomatoes like high nitrogen?

FarmProgress notes that tomatoes prefer a slightly acidic soil with a pH of 5.8 to 6.8. Soil that is depleted should use a fertilizer with a nitrogen, phosphorus and potassium mix of even amounts. A balanced NPK of 8-8-8 or 10-10-10 will ensure that the tomatoes have enough fertilizer to grow healthy and strong.

Where are the most nutrients in the ocean?

Probably the most important property of seawater in terms of its effect on life in the oceans is the concentration of dissolved nutrients. The most critical of these nutrients are nitrogen and phosphorus because they play a major role in stimulating primary production by plankton in the oceans.

Which ocean zone is lacking in nutrients?

The deepest part of the ocean, the abyssal zone, at depths of 4000 m or greater, is very cold and has very high pressure, high oxygen content, and low nutrient content. There are a variety of invertebrates and fishes found in this zone, but the abyssal zone does not have plants due to the lack of light.

What happens if you have too much nitrogen in your body?

Uremia is life-threatening because too much nitrogen in the blood is toxic to the body. Symptoms of uremia include confusion, loss of consciousness, low urine production, dry mouth, fatigue, weakness, pale skin or pallor, bleeding problems, rapid heart rate (tachycardia), edema (swelling), and excessive thirst.

What happens if plants get too much nitrogen?

When plants receive too much nitrogen (N), they become more attractive to insects and diseases. It can also cause excessive growth and reduce the strength of the stems.

Why are cold oceans more productive?

Why is cold water more productive? Cold water can hold more dissolved oxygen than warm water. The levels of dissolved oxygen in Antarctic waters are so high that many fish have few or no red blood cells (the blood cells other animals, including humans, use to carry oxygen).

What are the most productive waters in all the oceans?

In the focus: The oceans most productive areas. Although they occupy just fewer than two percent of the surface of the oceans, the large coastal upwelling areas on the eastern edges of the Pacific and the Atlantic are among the most biologically productive marine areas of all.

What lives in the Abyssopelagic zone?

Types of animals that live in the Abyssopelagic zone include algae, anemones, anglerfish, arrow worm, cookie-cutter shark, copepods, crabs, and other crustaceans, ctenophores, dinoflagellates, fangtooth, lantern fish (Myctophids), mussels, nudibranchs, some squid, segmented worms, siphonophores, swallower fish, …

Why are oceans important?

The air we breathe: The ocean produces over half of the world’s oxygen and absorbs 50 times more carbon dioxide than our atmosphere. Climate regulation: Covering 70 percent of the Earth’s surface, the ocean transports heat from the equator to the poles, regulating our climate and weather patterns.

Why is deep water rich in nutrients?

Deep waters are rich in nutrients, including nitrate, phosphate and silicic acid, themselves the result of decomposition of sinking organic matter (dead/detrital plankton) from surface waters.

Why is too much nitrogen bad?

Too much nitrogen and phosphorus in the water causes algae to grow faster than ecosystems can handle. … Excess nitrogen in the atmosphere can produce pollutants such as ammonia and ozone, which can impair our ability to breathe, limit visibility and alter plant growth.
