Term
the grouping which includes all the organisms which are interbreeding. The organisms can produce viable, fertile, offspring, but they can not produce viable fertile, offspring with another group of organisms
Definition
Biological Species
Term
the grouping which includes all the organisms which have the same shape and structure. many species were originally distinguished by this. if two organisms look alike they must be the same species.

Morphological Species
Term
based on the ability to reproduce. Individuals may look similar but not reproduce and therefore are not the same species or they may look different but can reproduce and therefore are the same species
