Three of the most prominent definitions of species are the biological species concept, the phylogenetic species concept, and the morphological species (morphospecies) concept. Match each characteristic with the species concept(s) to which it applies.
Species:
1. biological
2. morphological
3. phylogenetic
4. morphological and phylogenetic
5. biological, morphological and phylogenetic
Characteristics:
1) accommodates asexual reproduction
2) not applicable for extinct species
3) relies on similarities of structures
4) used by scientists in classification
5) species acceptance criteria can be subjective
6) based on evolutionary history

Biological species concept defines species as individual in a population that can interbreed and produce viable offsprings. Therefore Biological species concept is not applicable for extinct species

Morphological means in relation to structure therefore, this concept relies on similarity of structure to classify species.

Phylogenetic refers to members having the same ancestor. It classifies species according to common ancestry. Hence it will be based on evolutionary history.

Morphological and phylogenetic- Will accommodate asexual reproduction and species acceptance criteria can be subjective.  

Biological, morphological and phylogenetic-Together they are used by scientists in classification
