How is marine life affected by the viscosity of the ocean?

How does viscosity affect aquatic organisms? It takes more energy for them to travel through the water. ... It's water's resistance to organisms trying to penetrate its surface.

What kind of marine organisms are affected by changes in seawater viscosity with temperature?

A number of studies have shown that temperature-dependent viscosity of the ambient water controls or strongly affects bio-mechanical activity such as beat frequency of water-pumping cilia in mussels and ascidians, swimming velocity of sperm cells, ciliates and small (micro- and meso-scale) aquatic organisms using cilia ...

How does viscosity affect plankton?

Abstract. Seawater viscosity is influenced by temperature as well as through excretion of exopolymers by some plankton. ... Increased viscosity reduced distances between conspecifics 4.7-fold and increased distances between protists and microbeads by 3.4-fold.

How do marine mammals reduce drag?

The properties of the hair of aquatic mammals are noted to reduce drag by aiding in streamlining of the body. The lack of arrector pili muscles in seals and sea otter permits the pelage to lie flat in water minimizing resistance to swimming.

How do ocean currents affect animals?

When currents upwell, or flow up to the surface from beneath, they sweep vital nutrients back to where they're needed most. ... Because of upwelling nutrients, krill are abundant enough to feed the largest animals on earth, baleen whales, as well as myriad penguins, seals, and seabirds.

Which is an adaptation of aquatic animals to the greater viscosity of water?

In response to living in water, fast-moving aquatic animals such as fish, penguins, and whales have evolved highly streamlined shapes that reduce the drag caused by the high viscosity of water and other factors.

How do animals and plants of the ocean affect the chemical composition of seawater?

' The level of dissolved nutrients increases from animal feces and decomposition (bacteria, fungi). Surface water often may be lacking in nutrients because feces and dead matter tend to settle to the bottom of the ocean. Most decomposition is thus at the bottom of the ocean.

What is the importance of viscosity in aquatic environment?

The viscosity of water measures its resistance to flow and is critical to its many functions. The low viscosity of water is important in its role as the solvent for life's chemical reactions and for blood circulation.

What is viscosity of water?

The viscosity of water at a temperature of 20 degrees Celsius is approximately 0.01 poise or 10^-3 Pa. s (Pascal seconds). Viscosity is a measure of the resistance of a fluid to deformation at a given rate. For liquids such as water, viscosity can be perceived as a measure of the liquid's resistance to flow.

How does viscosity affect swimming?

The viscosity of water creates drag on swimmer's body so its effect is to slow down the swimmer. However the viscosity seems to be essential for pushing the water backwards by the swimmer's arms and legs.

Why does water become less viscous as you add heat?

The increase in temperature causes the kinetic or thermal energy to increase and the molecules become more mobile. The attractive binding energy is reduced and therefore the viscosity is reduced.

What does the word Nektonic mean?

(nĕk′tən, -tŏn′) The collection of marine and freshwater organisms that can swim freely and are generally independent of currents, ranging in size from microscopic organisms to whales.

What is drag marine mammals?

Drag can be thought of as the force that opposes movement of a body through a fluid (Reynolds & Rommel 23). ... Needless to say, this aspect of Fluid Dynamics is very important to marine mammals.

What are 2 reasons reducing drag is important to marine organisms?

The main reasons are their adaptability to environmental changes underwater and the ability to self-heal/correct the system. Cruising aquatic animals can utilize the surrounding environment to save energy. Also, the energy consumption of fish organisms in water is different from common sense.

What would happen to the marine animals eg fishes if there were no drag?

Answer: The ocean will no longer be able to perform many of its essential functions, leading to a lower quality of life. People will starve as they lose one of their main food sources.
