Abstract
The mathematical theory of human systems based on equations of state is also applicable for the model representation of the interaction dynamics of living systems, including a quantitative description of the life cycle of animals and their interactions.
The reason for this is the fact that both the life of humans and animals is a sequence of various actions that can be described by equations of state.
This also means that the universal method of equations of state must be in agreement with other known quantitative models representing the life and interactions of living systems.
The only way to prove the validity of such a statement is to derive the known quantitative models of living systems and their interactions basing on the method of state equations.
In this paper, it is shown that the behavior of the predator-prey system can be described by the method of equations of state, and based on this, one can easily obtain the differential equations of the famous predator-prey model of Lotka-Volterra in an analytical way.
This means that in the same way it is possible to obtain other known quantitative laws representing the behavior of living systems.
Moreover, such an approach also can make it possible to obtain analytically new patterns representing the possible manifestations of the behavior of living systems.
Introduction
All living systems, from the simplest organisms to people, society and civilization, in each situation are guided by the principle of ensuring the continuity and longevity of their life [1].
Since life at any level survives under conditions of various kinds of changes, in the event of an arbitrary change, the biosystem seeks to ensure the continuity of its life with maximum probability.
The course of life of an arbitrary biosystem is a sequence of actions, which is the response of this biosystem to the successive demands of life.
If the course of the life of a biosystem is stable and continuous, then there is a certain balance between the sequence of life requirements and the responses to these requirements on the part of the biosystem.
The concept of such a balance allows for a quantitative interpretation of the principle of continuity and longevity of life in the form of mathematical equations [1].
On the other hand, a quantitative interpretation of this principle is possible only if both the requirements of life and the responses of the biosystem to these requirements can be presented in a parametric form [2].
