A biological oxygen demand is another term for a biochemical oxygen demand - the amount of oxygen needed by aerobic microorganisms to decompose all the organic matter in a sample of water - used as a measure of pollution.

What are the relationship between cod chemical oxygen demand and bod5 biological oxygen demand what does the ratio of bod cod or cod bod means?
BOD is inversely proportional to COD
What biological processes releases oxygen into the atmosphere?
Photosynthesis.
What is Decreased by the breakdown of organic wastes?
Dissolved Oxygen
What biological process is responsible for the creation of oxygen in earth's atmosphere?
photosynthesis
What biological molecules contain oxygen?
They contain the same monomer subunits but they are arranged differently.
What is biological oxygen demand?
It determines the amount of dissolved oxygen that is consumed by aerobic biological microorganisms in water. It is measured by the amount of oxygen that is consumed per liter of sample during 5 days of incubation it is in milligrams.
What is the full form of bod related to water pollution?
Biological Oxygen Demand
What is mean chemical oxygen demand-?
The mean oxygen demand is the test done to indirectly determine the amount of organic compounds present in a water sample.
What are the relationship between cod chemical oxygen demand and bod5 biological oxygen demand what does the ratio of bod cod or cod bod means?
BOD is inversely proportional to COD
What is the different between biochemical oxygen demand and biological oxygen demand?
Oxygen Demand -The amount of oxygen require to oxidize an organic materialBiochemical (Biological) Oxygen Demand (BOD) -The amount of oxygen required to oxidized any organic matter present in the water by microbes present in the water. Usually representin the easily "digestible" organics.Chemical Oxygen Demand (CO) - The amount of oxidants experessed as oxygen required to consume all organics in a water sampleTotal Oxygen Demand (TOD) the sum of COD and BODBiological Oxygen demand is the oxygen required to oxidized only organic matter by micro organisms (it is basically a prototype of actual process happening in treatment plant) while chemical oxygen demand is the oxygen consumed to oxidize all organic and inorganic matter and it employ chemicals to do this process that why it is way more fast then BOD experiment .
How Biological Oxygen Demand (BOD) affects the aquatic life?
Biological oxygen demand is a measure e of how much oxygen microbes will use in decomposing organics in the water. It isa measure of how much oxygen is required to diffuse into the water to keep the ecosystem aerobic.
What is TOD BOD in water quality measurement?
There are three OD's used Total Oxygen Demand (TOD), Chemical Oxygen Demand (COD) and Biological Oxygen Demand (BOD) They all measure the amount of oxygen that would be required to consume organic material in the water, BOD is the lowest (usually) as it measures demand from microbes eating easily digested organics (sugars etc), COD measures the demand from all other organics (alcohols etc) measured by digesting the material in strong chemical oxidants, and TOD is the total of the two. Oxygen demand is important to know in waste handling as reducing the oxygen in receiving stream can harm fish and other aquatic life.
What is a biological role?
I believe it is the role for something (Substance or Being) in nature So oxygen molecules will have the biological role to supply the animal's blood with oxygen
Why is there a demand for chemical oxygen?
There is a very large demand for chemical oxygen. Chemical oxygen is very sought after because it can be used to determine when water is contaminated with pollutants.
What is BOD in chemistry?
Its full form is biological oxygen demand.Answer:The 5 day Biological Oxygen Demand (BOD5) is a measure of how much biologically usable dissolved organic material is present in a water sample. The units used are mg/liter (mg/L). The material can be eaten up bu microbes which remove oxygen in thee water. If this happens the low oxygen levels in the water make it unusable and or hazardous to fish.BOD5 is measured by putting a sample of the contaminated water in a sealed container, oxygenating it, then adding a microbial culture. The level of oxygen is measured at the end of 5 days and the concentration of organics is calculated.Companion tests include Chemical Oxygen Demand (COD) and Total Organic Carbon (TOC)
How does the baby lose oxygen?
by utilizing oxygen for biological processes without taking any additional oxygen in
Why bodincubator got that name?
The name bodincubator comes from the functional description of a piece of laboratory equipment called a Biological Oxygen Demand Incubator.Like a baby incubator its function is to maintain an environment - temperature, humidity, air-flow etc. - for biological subjects under investigation. The particular facility of this type of device is that it is hermetically sealed and can monitor/contol the level of oxygen in the system.Beano UK
