Levels of Organization• Living things have a highly
organized body structure, which allows them to perform all their vital functions. They may see a hierarchy that can be studied considering three levels of organization : chemical , biological, ecological .

Subatomic Level
• This level is the simplest of all and is made up of all subatomic particles such as electrons , protons and neutrons (composed of quarks) .
Atomic Level
• This consists of atoms constituting living beings are called bio-elements , including the most abundant are : carbon, hydrogen, oxygen and nitrogen .
Molecular Level
• Formed by the molecules that make up living things are called biomolecules , these in turn are divided into simple biomolecules , such as water, gas , minerals , amino acids , monosaccharides ; and complex biomolecules such as proteins , lipids , carbohydrates and nucleic acids. It is also called macromolecules .
Supramolecular Level
• At this level are the supramolecular associations resulting from the combination of two or more macromolecules such as cell membrane ribosomes cytoskeleton , etc.
Cellular Level
• It is the most important biological level because all living things are made of cells . Some are single-celled organisms (bacteria , consist of a single cell ) , while others are multicellular (animals, have many cells) .
Tissue Level
• It is formed by the tissues . A tissue is a group of cells that perform the same function. Examples epithelial , connective, muscle , nerve tissue .
Organic Level
• Made up of the organs. An organ of the grouping of various tissues , where they all work in coordination so that the organ hold a special function. Example : heart , brain, bone. Etc.
Sistemic Level
• It is composed of devices and systems. An apparatus resulting from the grouping of bodies composed of two or more varieties of tissues. For example : Digestive and Cardiovascular Apparatus. While a system results from the grouping of bodies composed of a single variety of tissue. For example : muscular and nervous system .
Individual Level• It refers to the multicellular
organism resulting from the grouping of devices and systems that work together in a coordinated manner and with great accuracy. Example : Man, cat, eucalyptus, etc.
Population
• A population resulting from the grouping of individuals of the same species inhabiting the same geographical area at a particular time, its members can reproduce and have fertile offspring .
Community
• A community results from the interaction of several populations of different species that share the same geographical area at a given time. Example : Galapagos island.
Ecosystem
• An ecosystem resulting from the interaction of a biotic community with the inanimate environment ( abiotic environment). Example : ecosystem " Sierra de Lobos"
Biosphere
• The biosphere is the grouping of the ecosystems of the earth, covering all of the planet inhabited by living things , I mean the atmosphere, hydrosphere and lithosphere.
