Which ecosystem has the greatest primary productivity ocean beds algal beds and reefs or estuary?

According to Whittaker (1975) of the three ecosystems, algal beds and reefs have the highest average primary productivity of 2500 g m-2y-1. Esturies are also fairly productive areas, averaging 1500 g m-2y-1. The open ocean on the other hand is a relatively unproductive system, averaging 125 g m-2y-1.

However, if you look at the total productivity, and not the averages, the picture changes substantially. Now the open ocean contributes the most to the total global productivity due to vastly greater area than either esturies or algal beds and reefs. Indeed, with just 1.2 x 109t-1 algal beds and reefs contribute the least to the total global productivity.

It is also worth noting that continental shelf areas have a higher productivity than open ocean, but contribute less to the global total, again because of reduced area.

What is composition of Fbc bed material?

A Fluidized Bed Combustor (FBC) typically uses sand or limestone as the bed material to fluidize and support the combustion process. The composition of the bed material can vary, but commonly it consists of silica (from sand) or calcium carbonate (from limestone). These materials provide stability and assist in heat transfer during combustion in the FBC.

How do you get permanent marker off a shrit?

Generally, you cannot get permanent marker off of a shirt; that's why it is called "permanent".

However, you can try saturating it with denatured alcohol and blotting it dry; this will remove SOME of the ink.

Vinegar is also sometimes a "miracle" cleaning solution.

How do you get semen stains out of bed sheets?

To remove semen stains from bed sheets, you can pre-treat the affected area with a mixture of cold water and laundry detergent before washing the sheets in cold water.

Can Reverse fault cause older beds to overlie younger beds?

No, reverse faults typically place older rocks on top of younger rocks. This is a result of compressional stress in the Earth's crust that pushes rocks upward and over each other along the fault plane.

What is the best mattress not to feel movement?

Memory foam mattresses are often the best for reducing motion transfer as they absorb movement and help prevent it from being felt on other parts of the bed. Look for a memory foam mattress with a high density and thickness to further minimize motion transfer. Additionally, hybrid mattresses with a combination of memory foam and pocketed coils can also offer good motion isolation.

Why do I sleep on the side of the bed nearest to the door?

How do you get urine stains out of mattress?

Could a dry but moldy 30 to 40 year old mattress and boxspring spontaneously combust over a 12 hour period once moved into open air on a humid day in the mid 80's?

Based on the conditions set out in your question, and my experience of two years as a Firefighter, and over 20 years as a Fire/Arson and Explosion Investigator, it is an impossibility for spontaneous combustion to occur under the conditions which you describe.

How do you get urine out of a mattress?

To remove urine from a mattress, blot up as much liquid as possible with paper towels, sprinkle baking soda to absorb any remaining moisture and odor, let it sit for a few hours, then vacuum it up. You can also create a cleaning solution using water, vinegar, and dish soap to spot clean the affected area. Allow the mattress to air dry completely before putting on clean bedding.

What are nitre-beds?

They stacked the "ingredients" on a bed of clay then left it till it formed a white crust, this was then removed and washed with water, this got rid of the other soluble products. They used then potassium nitrate to make gunpowder.

What chemicals are used to make a foam mattress?

One thing to look out for in foam mattresses is the use of PBDE's. These are flame retardants used to compensate the fact the foam is highly flammable.

PBDE's have been banned in Europe and are about to be banned in California.

This is because PBDE's or PolyBrominated Diphenyl Ethers have been found in humans. These particles are like the PCB's that were banned a few decades ago. They have been found to accumulate in humans (and animals) and not break down.

This has lead to concerns they might be carcinogenic. A pretty safe bet in avoiding PBDE's is buying organic or natural latex mattresses. Wool is also a natural flame retardant as so does not require PBDE's.

The dimensions of a water bed are 2.13 m by 1.52 m by 0.38 m If the frame has a mass of 91.0 kg and the mattress is filled with water whats the pressure the bed exerts on the floor?

2.13m x 1.52m x 0.38m = 1.230288 cubic metres = 1230.288 litres Assuming 1 litre of water = 1kg, gross weight of bed is 1230.288 + 91 = 1321.288kg 2.13m x 1.52m = 3.2376 square metres = 32376 square centimetres 1321.288 / 32376 = 0.040810724 kg/sq cm 0.40810724 x 1000 = 40.810724 g/sq cm (0.58046psi).

How will you make a simple levitating bed?

This is so easy it's ridiculous. It's also so expensive it's ridiculous. Buy about 150 pounds of samarium cobalt magnets (or 450 pounds of regular magnets), a gallon of Gorilla Glue and two sheets of plywood. Glue half the magnets to each sheet of plywood with either the positive or the negative poles facing up--your choice, but they've all got to be facing the same direction on both boards. Then get three friends to help you maneuver one sheet of plywood over the other one, making sure the magnets are facing down. The force of repulsion will levitate the bed. There is no such thing as a simple levitating bed. Expensive, complex ones exist, however. See the link: http://spluch.blogspot.com/2006/08/levitating-bed.html

Is it proper grammar to lie on the bed or lay on the bed?

It is proper grammar to say "lie on the bed" when referring to resting on the bed in a horizontal position without an object. "Lay" requires a direct object, so you would say "lay the book on the bed" when placing something on the bed.
