Abiotic - 🧠 ANSWER ✔✔Non-living, may be within or made by a living
organism.
Biotic - 🧠 ANSWER ✔✔Living. Matter is considered ______ if it was ever
alive at some point in time
Atom - 🧠 ANSWER ✔✔Smallest level. The basic unit of matter. Consists of
a dense nucleus surrounded by electrons.
,Molecule - 🧠 ANSWER ✔✔Second level. A chemical structure consisting of
at least two atoms held together by a chemical bond.
Macromolecule - 🧠 ANSWER ✔✔Third level. Biologically important
molecules that are technically polymers. Example: DNA.
Cell - 🧠 ANSWER ✔✔Fourth level. The fundamental unit of life. Essentially
a 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.
Organelle - 🧠 ANSWER ✔✔Fifth level. Compartments inside the cell that
contain 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 - 🧠 ANSWER ✔✔Sixth level. Single-celled life form.
Consists of just one cell and include unicellular organisms such as bacteria
and protists.
Tissue - 🧠 ANSWER ✔✔Seventh level. Formed when similar cells work
together to fulfill the same detailed function.
,Organ - 🧠 ANSWER ✔✔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 - 🧠 ANSWER ✔✔Ninth level. Consists of functionally related
organs. Mammals have many.
Organism - 🧠 ANSWER ✔✔Tenth Level. Individual living entities that
survive and reproduce as a unit. For example, each tree in a forest.
Population - 🧠 ANSWER ✔✔Eleventh level. Consists of all the individuals of
a species living within a specific area.
Community - 🧠 ANSWER ✔✔Twelfth level. Populations can interact with
each other in positive and negative ways, and together they form this.
Ecosystem - 🧠 ANSWER ✔✔Thirteenth level. Consists of all the living
things in a particular area together with the abiotic, or nonliving, parts of
that environment.
Biosphere - 🧠 ANSWER ✔✔Fourteenth level. The highest level of
organization in living systems. The collection 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 - 🧠 ANSWER ✔✔Characteristics of a system that are
not present in any of its component parts.
Biology - 🧠 ANSWER ✔✔The scientific study of life and is the branch of
science that studies living organisms and the way organisms interact with
their environments.
Homeostasis - 🧠 ANSWER ✔✔The ability or tendency of organisms and
cells to maintain stable internal conditions.
Nutrient - 🧠 ANSWER ✔✔Any matter an organism needs but cannot make
for itself.
Energy - 🧠 ANSWER ✔✔The capacity to do work or to make a change in
the location, temperature, or structure of matter. Does not have mass and it
does not take up space, but it can be measured in terms of what it does.
Growth - 🧠 ANSWER ✔✔An increase in size.
