Homozygous, or pure bred.
dominant
Truebreeding
One celled organisms are called unicellular organisms.
Organisms that are divided into classes are called classifying organisms or classified organisms.
Organisms that eat other organisms are called consumers or predators.
These organisms would be called mutants.
The process by which modern organisms have descended from ancient organisms is called evolution.
Purebred is only possible in Homozygous conditions such as AA or aa, and indvidual that is a hybrid (Aa) is not truebreeding and therefore is not purebred.
dominant
Organisms that hunt and kill other organisms for food are called predators.
Those organisms are called heterotrophic. These organisms either eat the autotrophs (organisms that make their own food) or eat the organisms that eat the autotrophs (also called the producers). Heterotrophs are also called "consumers."
Parasites.
