•  Biosphere

  The biosphere is the global sum of all ecosystems. It can also be called the zone of life on Earth. From the broadest biophysiological point of view, the biosphere is the global ecological system integrating all living beings and their relationships, including their interaction with the elements of the lithosphere, hydrosphere, and atmosphere. The biosphere is postulated to have evolved, beginning through a process of biogenesis or biopoesis, at least some 3.5 billion years ago.

•  Ecosystem

  The term ecosystem refers to the combined physical and biological components of an environment. An ecosystem is generally an area within the natural environment in which physical factors of the environment, such as rocks and soil, function together along with interdependent organisms, such as plants and animals, within the same habitat. Ecosystems can be permanent or temporary. Ecosystems usually form a number of food webs.

•  Irreducible complexity

  Irreducible complexity (IC) is an argument by proponents of intelligent design that certain biological systems are too complex to have evolved from simpler, or "less complete" predecessors, through natural selection acting upon a series of advantageous naturally occurring chance mutations. It is one of two main arguments intended to support intelligent design, the other being specified complexity.

•  Magnesium in biology

  Magnesium is an essential element in biological systems. Magnesium occurs typically as the Mg ion. It is an essential mineral nutrient for life and is present in every cell type in every organism. For example, ATP (adenosine triphosphate), the main source of energy in cells, must be bound to a magnesium ion in order to be biologically active. What is called ATP is often actually Mg-ATP. .

•  Biota (taxonomy)

  In some systems of scientific classification, Biota or Vitae is the superdomain that classifies all life. For that reason it is often disputed how the taxon should be further divided, as the definition of what life really it is often changed or adjusted, and also extraterrestrial life would be included besides the life on Earth, if extraterrestrial life is discovered.

•  Living systems theory

  Living systems theory is a general theory about the existence of all living systems, their structure, interaction, behavior and development. This work is created by James Grier Miller, which was intended to formalize the concept of life.

•  Biological system

  In biology, a Biological system (or Organ system) is a group of organs that work together to perform a certain task. Common systems, such as those present in mammals and other animals, seen in human anatomy, are those such as the circulatory system, the respiratory system, the nervous system, etc. A group of systems composes an organism, e.g. the human body.

•  Ecosystem model

  Ecosystem models, or ecological models, are mathematical representations of ecosystems. Typically they simplify complex foodwebs down to their major components or trophic levels, and quantify these as either numbers of organisms, biomass or the inventory/concentration of some pertinent chemical element.

•  Developmental systems theory

  In biology the developmental systems theory (DST) is a collection of models of biological development and evolution that argue that the emphasis the modern evolutionary synthesis places on genes and natural selection as explanation of living structures and processes is inadequate.
