Describe the biological species concept.

a concept that classifies organisms as being from the same species if they are able to interbreed to produce fertile offsprings.

Identify limitations of the biological species concept.

1. Asexual reproducers
2. Extinct Species
3. Practicality
4. Physical isolation
5. Habitat differences
6. Incomplete speciation (developing)
7. Races and sub-species (sometimes they can interbreed but not always)

what are hybrids in the context of the biological specie concept?

hybrids occur when two similar organisms breed together to produce sterile offsprings.

what is classification?

The organisation of items into particular groups.

Who invented the Linnaean system and what is it?

A hierarchical

How are things named in the Linnaean System of Classification?

has seven levels that gets more specific as you progress.
