Naming an organism with its genus and species name:
Reproduction accomplished by a single organism:
A unit of one or more populations of individuals that can reproduce under normal conditions, produce fertile offspring, and are reproductively isolated from other such units:
The sum total of all processes in an organisms which convert energy and matter from outside sources and use that energy and matter to sustain the organism's life functions:
Organisms that eat only organisms other than plants:
Organisms that eat both plants and other organisms:
The idea that long ago, very simple life forms spontaneously appeared through chemical reactions:
All life forms contain:
All life forms can sense in their surroundings and to those changes
All life forms have a method by which they extract from the surroundings and convert it into that sustains them
All life forms
Reproduction that requires two organisms:
Organisms that depend on other organisms for their food:
Special structures that allow organisms to sense the conditions of their internal or external environment:

Organisms that are able to make their own food:
The sum total of all processes in an organism which break down chemicals to produce energy and simple chemical building blocks:
