Population, in human biology, the whole number of inhabitants occupying an area (such as a country or the world) and continually being modified by increases (births and immigrations) and losses (deaths and emigrations). As with any biological population,

For a full definition of the model the initial state of the system has to be specified, that is, the numbers or fractions of the population in the states S, I, and R at time t = 0 have to be prescribed. Values for the parameters ν, μ, γ, and β have to be chosen, either ...
they are provided, are greater in the organic system. Therefore, the two conditions of greater abundance of individuals contributing to each function and greater diversity within each functional class resulting in greater complementarity of function among microhabitats satisfy the definition of soil ...
