The living beings are those beings In particular, they have a complex organic structure, and they fulfill a cycle through which they are born, grow, reach a capacity to reproduce and then die. For instance: fish, birds, humans, protozoa.
The features that are characteristic of living beings are those of homeostasis (the balance between the external and internal environment, fundamental for the condition of life), the organization of cells, metabolism, irritability, adaptation and the reproduction.
By the characteristic of living beings to be autonomous, It is necessary to say that on planet Earth the multiplicity of living species has led to a forced coexistence, through which different species of beings saw the need to interact with each other.
The supremacy of the human being It was a crucial point in this order, since the relationship with other living beings began to be realized from another point of view, such as trade, culture or different motives typical of a civilization.

Non-living beings
The denomination of non-living beings many times it is used to speak of inert objects, those that cannot fulfill any of the vital functions of living beings. For instance: rocks, sand, plastic, water.
Nature is endowed with a large number of objects that do not have the characteristics of living beings, some of them essential for life but not endowed with it. In addition, the transformation that living beings have carried out on earth caused a much greater number of inert objects to be produced, among which all the objects that human beings have built on their path of development appear.
The process of the inert matter In relation to its reproduction it has certain characteristics, which will never be the same as those of living beings. Here are some examples of inert objects:
