In a world that surrounds us, there are several different levels of interrelated biological, obeying a single hierarchy.Depending on their complexity emit eight levels of the structural organization of wildlife.
First on the list - molecular.It begins with his levels of the organization alive.The object of research at this level are molecules of proteins, carbohydrates, fats.It also includes lipid molecules, nucleic acids and deoxyribonucleic and other macromolecules that comprise any living cell.It begins at the molecular level the processes of life, even the most complex organism: the transformation of energy, transmission of hereditary traits, metabolism and so on.
Continues levels of organization of the living cell level.As is known, the cell - is a structural and functional unit, without which no life, development and reproduction.It is the unity of all living beings, both unicellular and multicellular.
levels of organization of living continues tissue level.Fabric - a set of cells and intercellular substance, which combines similar origin and function performed.According to one classification, there are six types of tissues in the plant body and four animals.The plant is: education, the coating, mechanical, excretory, and the main conductive fabric.The animals distinguish epithelial, muscle, nerve and connective, and each of them has certain properties and performs other distinctive features.For example, nerve tissue communicates organs, tissues and systems of the body, as well as engaged in their regulation.With it comes the signals from the outside world, the reception and transmission of nerve endings.
in levels of structural organization of wildlife includes the organ level.Under the authority of the understanding of a multicellular organism, has a definite shape and perform any function.This functional unit is mostly made up of several types of tissue, one of which predominates.In addition, the body can only be considered in isolation from other functional units of the.For example, human organs are: the pituitary gland, stomach, intestines, uterus, adrenal glands, liver, heart, etc.
continuing levels of organization of a living organism levels, which in turn are divided into unicellular and multicellular.The simplest single-celled organism, it becomes clear from the name, consists of a single cell and multicellular forms a set of tissues and organs.
next level - the population-species.Under the population understand the totality of individuals or organisms similar in structure, living in a certain area, not isolated from other areas, between which the crossing.On the planet today were more than 1.5 million. Animal species and about 500 thousand species of plants.
the penultimate place is biogeocenotic level.Under bio- geocenosis droop historically developed a set of different types of interacting with their environment.At this level, there is the cycling of matter and energy, in fact it is a self-regulating ecosystem resilience.
Completes Biosphere system level of organization of life.He combines various global biogeocoenoses.In the biosphere, the origin of all cycles of energy and matter in the world, connected with the life of all organisms living on the planet.
Although the levels of organization of living divided into eight parts, they are all interrelated.At the same time, each level has its own characteristics, patterns and methods.
