Dimension of Biological resources:
There is complexity of relationship between four dimensions of
 biological resources.
•Quantity is indicated by Biomass or number of species, but it 
does not capture the economically important quantity dimension
•Mass volume and population size  may be relevant measure of 
quantity of biological resources


•Quality: It is defined in terms of intended use, what really constitutes the high quality may conflict, given different valuation of alternative uses
•E.g. A mono-culture of high yielding GMO variety may be considered high quality for emphasizing food production, but it can be low quality for ecological continuity and aesthetics
•Time  dimension is the time period during which certain stock of resource is determined, used and regenerated
•Space/ Place dimension: It includes the habitat or the territorial ranges where there is high possibility of successful growth of some species and migratory pattern of other

CORONA VIRUS !!! The corona virus case began in Wuhan China since December 2019 AD.Later on it spread to other countries like Korea, America, Italy, Iran, Japan, India including most of the Asian and European countries of the world. WHO named it a Pandemic disease as it appeared in almost all continents of the world. Several countries went in lock down including China, India, Russia, Nepal etc. China and Italy had highest death rate. It was found that, this virus effects the respiratory tract.  The symptoms includes: Running nose,  Fever, Shortness of breathe leading to pneumonia The death rate was highest among aged people above 80 years old. However it affects almost all age groups. Viral disease has no cure rather than improving immunity.So, take care of yourself everyone. If anyone gets infected, isolate yourself.Protect yourself and your loved ones.

Least cost Combination (LCC) • There are innumerable possible combination of factors which can be used to produce a particular level of output. • The problem is to find out the combination of inputs which should cost least, a cost minimization problem. • There are three methods to find out the least cost combination of inputs. They are: • Arithmetical Method: • Algebraic Method: • Graphic Method: 1. Arithmetical Method: • One possible way to determine the least cost combination is to compute the cost of all possible combinations of inputs and then select one combination with minimum cost. • This method is suitable where only a few combination produce a particular level of output.  • The product produced is 100 kg, • Price of x1 input is Rs 3 per unit and price of x2 is Rs 2 per unit 2. Algebraic  method: a. Compute marginal rate of technical substitution. • MRS = Number of units of replaced resources/Number of units of added resources. • MRS X1

Marginal rate of product substitution (MRPS): • MRPS refers to the absolute change in one product associated with a change of one unit in competing product. The quantity of one product to be sacrificed so as to gain another product by one unit in called MRPS. • MRPS= number of units of replaced product/number of units of added product • MRPS Y2Y1= Δ y1/ Δ y2
