the system of nomenclature in which two terms are used to denote a species of living organisms. The first word is the genus and the second is the specific epithet.

an organism that feeds on or breaks down dead plant and animal matter

an organism that gets its own food inorganic substances (carbon dioxide and ammonia)

a tissue, organ, or organism made up of many cells

A scientific name is a two-word name which is unique to a particular organism, unlike a common name where there may be several different common names for the same organism

an animal that cannot produce its. own food and must eat plants or. other animals for energy.

an organism that cannot synthesize its own food and is dependent on organic substances for nutrition

the assignment of organisms to groups within a system of categories

a structural layer surrounding some types of cells just outside the cell membrane

These names are important because they allow people throughout the world to communicate about animal species.

any organism that lacks a nucleus and other organelles because they do not have internal membranes

A way to classify themes in nature. For example, in tree identification, a dichotomous key might ask whether the tree has leaves or needles.

an organism that produces/makes its own food (example: plants and algae)

all living organisms are classified into groups based on basic shared characteristics

Archaebacteria, eubacteria, fungi, protists, plants, and animals

having or consisting of one cell

the process used by plants, algae, and certain bacteria to take energy from the sunlight and use it for its own energy

protists are single-celled

Linnaeus

genus and species

a system of classifying organisms, the classification of living and extinct organisms

any cell or organism with a clearly defined nucleus

a group of living organisms consisting of similar individuals capable of exchanging genes or interbreeding

The classification of living things includes 7 levels: kingdom, phylum, classes, order, families, genus, and species

The scientific names of species are italicized. The genus name is always capitalized and is written first; the specific epithet follows the genus name and is not capitalized.
