Deer Killed per Predator = WITH LOOKUP (
	Deer Density/Initial Deer Density,
		((0,0),(1,2),(2,4),(4,6),(5,6) ))
	~	Deer/(year*lion)
	~	When density is equal to 0, the deer killed are 0. Point (0.0). When the \
		Deer Density is equal to the Initial Deer Density each predator hunts 2 \
		deer each year. Point (1,2).
	|

Deer Predation Rate=
	Deer Killed per Predator*Predator Population
	~	Deer/year
	~		|

Initial Deer Density=
	200
	~	acre/Deer
	~	1,000,000 acres / 5,000 deer
	|

Growth Rate Factor=
	0.2
	~	1/year
	~	Here we work with the net growth rate of the deer population. This means \
		birth minus deceases. If every female had a fawn, the rate will be 0.50% \
		But there are female too old and too young to have fawns, so we reduce \
		this amount to the 0.30%. Now we need to consider the life expectancy, may \
		be 10 years. This is - 0.10% due to deceases. So we assume the Net Growth \
		Rate Factor equal to 0.2

Area=
	1e+006

Deer Population= INTEG (
	+Deer Net Growth Rate-Deer Predation Rate,
		5000)
	~	Deer
	~	Initial amount of deers is 5,000 and remains constant.
	|

Deer Density=
	Area/Deer Population
	~	acre/Deer
	~	This is the amount of acres per deer
	|

Deer Net Growth Rate=
	Deer Population*Growth Rate Factor
	~	Deer/year
	~		|

Predator Population=
	500
	~	lion
	~	We assume that Net Growth Rate was 1000 deer, so Deer Predation Rate must \
		be also 1000 deer. In Table 1 we define that with a density of 0.005 \
		deer/acre are killed 2 deer/predator, so we have  1000 (deer) /2 \
		(deer/predator) = 500 predators
