What is the sequence of levels of organization of living matter, observing the principle of hierarchy.

The first level is molecular. The elementary units of this level are biomolecules: nucleic acids, proteins, lipids, carbohydrates and other organic compounds. The next level of organization of life is the cellular level. The elementary units of this level are cells. The cells, interacting, form the tissues from which organs are formed. Organs and tissues represent the organ-tissue level of organization of life. Organizational level of life organization is represented by organisms (individuals) – integral self-regulating systems consisting of interconnected tissues and organs. The next level of life organization is population-specific. The next level of organization of life is biocenotic. The elementary units of this level are biocenoses (communities). The biogeocenotic (ecosystem) level of organization of life is even more complex, since it is represented by biological systems – biogeocenoses (ecosystems), which arise as a result of the interaction of biocenoses and environmental conditions. The highest level of organization of life is the biosphere. The totality of all ecosystems on planet Earth.

Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
