Nitrogen in the air enters and leaves living systems by way of the nitrogen cycle. Describe the events which take place when atmospheric nitrogen molecules move along a food chain (involving legumes and herbivorous mammals) and eventually return to the atmosphere. In your answer‚ describe the uptake‚ processing and utilization of nitrogen in the bodies of these organisms Atmospheric nitrogen in air enters by diffusion or gaseous exchange and leaves the bodies of most organisms without biotransformation

The Laffer curve‚ named after the economist Arthur Laffer‚ is a curve that demonstrates the trade-off between tax-rates and tax-revenues (Wanniski 1978). It is used to illustrate the concept of taxable income elasticity‚ the idea that a government can maximise the revenue by setting the tax rates at an optimum point. This curve can be traced back as far as 1844 to a French economist Jules Dupit who in 1844 found similar effects as Laffer did (Laffer 2004). Dupit also saw tax revenues rising from

Hubbert’s prediction that oil reserves behave in a bell curve and that the world’s oil production will peak and drop exponentially‚ underlines Georgescu-Roegen’s point that natural resources are indeed limited.

Learning Curve Primer The concept of a Learning Curve is motivated by the observation (in many diverse production environments) that‚ each time the cumulative production doubles‚ the hours required to produce the most recent unit decreases by approximately the same percentage. For example‚ for an 80% learning curve: If cumulative production doubles from 50 to 100‚ then the hours required to produce the 100th unit is 80% of that for the 50th unit. The learning curve formula can be expressed
