Classification
Carolus Linnaeus
The process of organizing
living things into groups so
that they can be studied
more easily.
18th Century Swedish
botanist who devised a
system of classifying and
naming organisms
Binomial Nomenclature
The practice of giving every
living thing a two word
name based on its genus and
species

 How they obtain food
Autotrophs
Organisms that can make their own
food using carbon dioxide and water.
(Photosynthesis and chemosynthesis
are two food-make processes of
autotrophs.) Plants are autotrophs.
Heterotrophs
Organisms that cannot make
their own food. They have to
get their food. Animals and
fungi are heterotrophs.
Organisms that have their
genetic material enclosed in
in a nucleus
Eukaryotes
Prokaryotes
Organisms that do not have
their genetic material
enclosed in a nucleus

Community
Ecosystem
Organisms that consist of
one independent cell. The
single cell carries on all life
activities.
Organisms that are made up
of more than one cell

living things on Earth
An organism’s role in its
environment
An integrated group of
species that live in a specific
area. They influence each
other is several ways.
The living members of a
habitat interacting with their
non-living environment,
such as rocks, water, etc.

Needs of Living Things
Captive Breeding
Living things are made of
cells, are composed of
specific chemicals, use
energy, grow and develop,
respond to their
environment, and reproduce.
Living things need a source
of energy, water, living
space, and a stable internal
environment (homeostasis).
