Explanation

Attributes ;_;

FoodUnitsNeeded ;_;

The amount of food needed per period, but this current value is just the default and can change based on the formula in the animal class.

FoodUnitsConsumedThisPeriod ;_;

This value is the amount of food eaten this period.

DefaultLifespan ;_;

The average lifespan of the Animal sub class Fox but of course there is some variance.

DefaultProbabilityDeathOtherCauses ;_;

The default chance that the fox will die to causes other than starvation or old age.

Methods

Fox

This method creates a fox using its base class Animal, with the lifespan and death from other causes probability of fox and Variability stated in the program.
