What is the population in terms of biology?Scientists give such a definition: it is a certain number of individuals living in the same territory, having a genetic community and ability to reproduce.
population genetic structure is the main factor that brings together individuals of a species.It affects not only play, but also the organization of production of food on intraspecific relationships.You can give an example.The researchers decided to find out what will one species in different conditions.The experiment was conducted in the laboratory.Two broods locusts were placed in transparent containers.One consisted of five individuals, one - hundred.Initially, development was identical.In both containers were given the same amount of food.The small insect population continues to behave quietly, they were large, non-aggressive.In a large - insects always had difficulties: the food was not enough, and the space was limited.These individuals are much smaller in size compared to the relatives fed and very aggressive.They quickly got up on the wing.But the lack of food has led to the fact that the locusts did not multiply, and many began to hurt.This experiment demonstrates that a population and how it varies depending on environmental conditions.
Empirically, it has been proven that the welfare of the form depends on how successful the process of reproduction and development of new territories.It enters the static and dynamic characteristics of the population.The first - say, as a separate part of the same species can reproduce itself.Second - how the population is able to occupy a large area, and its representatives - to adapt to environmental changes.
What is the population in terms of ecology?This concept is seen primarily as a factor in the changing environment.That is, one population of a species leading livelihoods in a particular area, to actively influence a change in the living conditions not only of its kind, but also others.An example is still the same locusts.When its population increases to a very large size, it becomes a wing, it begins to migrate, eating everything in its path.Thus, growth of populations of one species leads to the destruction of others.
What is the population of the human species?This is a very interesting question.Mankind takes up most of the planet's surface.Homo Sapiens refers to those species that are most actively changing the environment in the course of his life.The very human population is growing quite rapidly.And there is a fear that nature will begin to control our reproduction.She has many ways to affect the population.This is a limitation of food resources, fresh water, infectious diseases that can cause serious epidemics.That is to say, natural ways.In addition, there are factors that affect the emotional and mental state: increased aggression and competition for resources.
