The level of dissolved oxygen in water can decrease after sunset due to the lack of photosynthesis by aquatic plants. Without sunlight, plants stop producing oxygen through photosynthesis, while organisms in the water continue to consume oxygen through respiration, leading to a decrease in dissolved oxygen levels.

Why does the level of dissolved oxygen go down after sunset?
noAnswer:There are several factors that could impact the levels of dissolved oxygen in natural water during the evening and night time. None of these are over riding enough to state that the DO levels would go up or down in all situations:* Cooler temperatures would increase the solubility of oxygen in the water. Oxygen already in the water would tend to stay there. * Temperatures in the water would go down decreasing the activity of any decomposition, slowing the reduction of oxygen levels. * Plants (algae etc.) would stop producing oxygen by photosynthesis* Plants would continue their respiration and consume oxygen * Winds are often calmer in the evening reducing aeration of the water through wave action
What is the effect of temperature on the amount of oxygen that water a different temperatures can hold?
As temperature increases, the amount of oxygen that water can hold decreases. Warmer water has lower oxygen solubility than colder water. This reduction in oxygen solubility can negatively affect aquatic organisms that rely on dissolved oxygen for survival.
Why do you sweat more at sea level than at high elevation?
You sweat more at sea level than at high altitude because the air is warmer and more humid at lower altitudes, which increases your body's need to cool down through sweating. Additionally, at higher elevations, the lower oxygen levels place less stress on the body, reducing the need for sweating to cool down.
What breaks water into hydrogen and oxygen?
Electrolysis breaks water into hydrogen and oxygen. When an electric current is passed through water, the water molecules (H2O) are split into hydrogen gas (H2) at the cathode and oxygen gas (O2) at the anode.
High oxygen to low oxygen?
From areas of high oxygen concentration to low oxygen concentration, diffusion occurs as oxygen molecules move down their concentration gradient, from where there is more oxygen to where there is less oxygen. This process enables the cells in the body to take in oxygen and use it for cellular respiration, supporting various physiological functions.
Why does the level of dissolved oxygen go down?
Dissolved oxygen levels can decrease due to processes like respiration by aquatic organisms, decomposition of organic matter, and insufficient mixing of water. Pollution, high temperatures, and excessive plant growth can also lead to decreases in dissolved oxygen levels in water bodies.

What is the function of a dearator on a steam boiler?
Deaerator removes dissolved oxygen from boiler water. The condensate cascades down a number of perforated trays and its surface area is greately increased. This enables dissolved oxygen to come out. Further bleed steam is supplied to deaerator and due to this the atmosphere is predominantly of steam. So the partial pressure of oxygen above the water level is very very low. When a gas exists above a liquid level, the solubility gas in the liquid depend upon its partial pressure. So oxygen comes out of water. Deaerator outlet water has less than 0.05 ppm dissolved oxygen. This is furthe removed by dizing of Hydrazene (N2H2). =A.D.PALAMWAR
When was Down on Sunset created?
Down on Sunset was created in 1991.
What is the relationship between bod and do?
BOD (biological oxygen demand) is a measure of the amount of oxygen needed bymicrobes to break down the organic matter in a sample of water. DO (dissolved oxygen) is the amount of oxygen dissolved in the water. When BOD is high, it means there's a lot of organic contaminants in the water, and the microbes are working overtime to break it down. They use up oxygen while doing this, so when BOD is high, DO is low. When the microbes finish breaking down the organic contaminants, their numbers drop from lack of food (a lower BOD). DO usually goes back up again
Why does the nitrogen level in the atmosphere is higher than the oxygen level?
Nitrogen is more abundant in the atmosphere than oxygen because nitrogen is about 78% of the atmosphere while oxygen is about 21%. This is due to the way the atmosphere was formed and the balance of gases that resulted from geological and biological processes over time.
How are chemical bonds dissolved?
Chemical bonds are not dissolved they are broken down and compounds becomes dissolved.
What breaks down tin?
Tin can be broken down through chemical reactions such as oxidation by oxygen in the air. It can also be dissolved in strong acids or alkalis to break down into tin compounds. Additionally, tin can be broken down through electrolysis processes.
What bodies of water have more dissolved oxygen?
Fast flowing mountain streams have more dissolved oxygen than slow flowing rivers down in the flat valleys. The oxygenation is higher because the tumbling water of the mountain stream increases the area open to absorption.
Has a nervous system blood vessels and a long digestive tube that runs down the length of its body It can also absorb dissolved oxygen through its skin what is it?
segmented worm that is the answer
How is oxygen taken in into the body tissue?
At the level of the capillaries, oxygen will diffuse out of the saturated red blood cells down their concentration gradient into the tissues where their concentration is lowest.
How do the lungs get the oxygen to the body?
The air enters through the mouth or the nose and is pulled down through the windpipe into the lungs. From the lungs, the oxygen molecules are dissolved in the alveoli and enter the red blood cells in the capillaries of the lung. From the capillaries, they travel to the heart and push oxygen through the body.
