Abiotic Non-living, may be within or made by a living
organism.
Biotic Living. Matter is considered if it was ever alive at
some point in time
Atom Smallest level. The basic unit of matter.
Consists of a dense nucleus surrounded by
electrons.
Molecule Second level. A chemical structure consisting
of at least two atoms held together by a
chemical bond.
Macromolecule Third level. Biologically important molecules
that are technically polymers. Example:
DNA.
Fourth level. The fundamental unit of life. Essentially a
Cell tiny droplet of water and
other molecules enclosed by a fluid "skin" or
membrane. The smallest and simplest entity
that possesses all the characteristics of life.
Fifth level. Compartments inside the cell that contain
Organelle specific groups of
macromolecules and carry out specific cellular
functions. One of these organelles is the
nucleus; it encloses the DNA within the
cell.

Microorganism Sixth level. Single-celled life form. Consists of
just one cell and include unicellular
organisms such as bacteria and protists.
Tissue Seventh level. Formed when similar cells work
together to fulfill the same detailed function.
Organ Eighth level. Collections of tissues that work
together to carry out a common general
function. Present not only in higher level
animals but also in plants.
Organ System Ninth level. Consists of functionally related organs.
Mammals have many.
Organism Tenth Level. Individual living entities that
survive and reproduce as a unit. For example,
each tree in a forest.
Population Eleventh level. Consists of all the individuals of
a species living within a specific area.
Community Twelfth level. Populations can interact with
each other in positive and negative ways, and
together they form this.
Ecosystem Thirteenth level. Consists of all the living
things in a particular area together with the
abiotic, or nonliving, parts of that
environment.
Fourteenth level. The highest level of
organization in living systems. The collection
Biosphere
of all ecosystems on Earth. Includes all
habitable zones on the planet, including
land, soil, and rocks to a great depth in the
Earth's crust; water and ice; and the
atmosphere to a great height.
Emergent Properties Characteristics of a system that are not present in
any of its component parts.
Biology The scientific study of life and is the branch of
science that studies living organisms and the
way organisms interact with their
environments.
