What is the different between biochemical oxygen demand and biological oxygen demand?
Oxygen Demand -The amount of oxygen require to oxidize an organic material
Biochemical (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 sample
Total Oxygen Demand (TOD) the sum of COD and BOD
Biological 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 .

What is difference between slope and the calculation of elasticity for a linear demand curve?
Along a linear demand curve elasticity varies from point to point of the demand curve with respect to different price, but slope is constant
What is the relationship between the demand schedule and the demand curve in economics?
The demand schedule and the demand curve in economics both show the relationship between the price of a good or service and the quantity demanded by consumers. The demand schedule is a table that lists different prices and the corresponding quantities demanded, while the demand curve is a graphical representation of this relationship. The demand curve is derived from the demand schedule, with price on the vertical axis and quantity on the horizontal axis. Both the demand schedule and the demand curve illustrate how changes in price affect the quantity demanded, showing an inverse relationship between price and quantity demanded.
What is the difference between a demand curve and a demand schedule, and how do they each represent the relationship between price and quantity demanded in economics?
A demand curve is a graphical representation of the relationship between price and quantity demanded, showing how the quantity demanded changes as the price changes. A demand schedule, on the other hand, is a table that lists the quantity demanded at different prices. Both the demand curve and demand schedule illustrate the law of demand, which states that as the price of a good or service decreases, the quantity demanded increases, and vice versa.
What relationship is shown by the aggregate demand curve?
The aggregate demand curve shows the relationship between the total quantity of goods and services demanded in an economy at different price levels.
What is a biological oxygen demand?
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 does bod stand for?
BOD commonly stands for "Biochemical Oxygen Demand." It is a measure of the amount of dissolved oxygen consumed by biological organisms in water. High BOD levels indicate organic pollution and can lead to oxygen depletion in aquatic systems.

What is a full form of BOD?
In chemistry b.o.d means " biochemical oxygen demand "
Differences between Primary and selective Demand?

What is organic loading rate?
Organic loading rate (OLR) is a measure of the amount of organic matter being fed into a biological treatment system per unit of time. It is typically expressed in terms of chemical oxygen demand (COD) or biochemical oxygen demand (BOD) per unit volume of the system. OLR is an important parameter in designing and operating biological treatment systems such as anaerobic digesters or activated sludge systems.
Does a biological oxygen demand value would be a negative value?
The only way a biochemical oxygen demand value could be negative is if oxygen increased in your incubation. This could result from several errors, but most likely light was allowed to penetrate your bottle allowing photosynthesis to occur. If everything was done correctly (e.g. insturments are calibrated and working, no errors were made in calculations) you should have at least a 1mg/L difference between initial and final dissolved oxygen readings yielding a positive value.
WHAT IS DIFFERENT BETWEEN DEMAND AND REQUEST?
A demand is almost like a NEED for something, while a request is just asking for something whether you need it or not.
What is different between supply and demand?
Demand is the pressure that we put on the environment is order to meet our needs and wants but Supply is the resources that are taken from the environment.
What causes biochemical oxygen demand?
Biochemical oxygen demand (BOD) is caused by the presence of organic pollutants in water, such as sewage, agricultural runoff, and industrial effluents. These organic pollutants provide a food source for bacteria, which consume oxygen as they break down the pollutants, leading to a decrease in oxygen levels in the water.
