What is the organization of living beings?

In biology it is known that every living being is composed of cells, some of a single cell and others of groups of cells that unite to form tissues, and in turn tissues that form organs, organs that form organic systems and organic systems that are combined to form multicellular organisms.

Wich are the levels of organization?

Individual organisms can be classified as follows from the basic unit to the organism itself.

  • Cell: Basic unit of all living things with its own structure and function.
  • Tissue: Group of cells of the same type that clump together.
  • Organs: Structure composed of one or more specific types of tissue, which work together to fulfill a specific function.
  • Organic System: Group of organs that work together to fulfill a certain function.
  • Organism: An individual living being that can be composed of one or more organic systems.
A mouse is made up of several organ systems. The system shown here is the digestive system, which separates food into a shape that a cell can use. One of the organs of the digestive system is the stomach. The stomach, for its part, is made up of diff

There are also levels of organization beyond individual organisms, since organisms of the same species living in the same area form a population. For example, all goldfish living in the same area form a goldfish population.
Likewise, all the populations that live in the same area form a community. Using the same example, a community would be one that includes the population of goldfish, other fish, corals, and other organisms.
A group of communities in a specific area, together with the inert environment, including water, sunlight, and other physical factors; it forms an ecosystem.
A group of similar ecosystems with the same type of physical environment is called a biome.
The biosphere is the part of the Earth where all life exists, including the land, and the air where living things can be found. The biosphere is made up of many different biomes.

Biodiversity

On planet earth there are various animal and plant species that interact with each other in an ecosystem, it is believed that there are at least 10 million different species living on our planet today. Which normally are grouped into six different kingdoms, this is known as Biodiversity.

These six kingdoms are part of the classification of living beings based on their characteristics, which are Archaea, Eubacteria, Protista, Fungi, vegetalia and animalia.
