Group of answer choices

The ecological species concept

The morphological species concept

The biological species concept

The phylogenetic species concept

Expert Solution

Answer - The ecological species concept

Explanation -

1. Ecological species concept - It defines a species in terms of its ecological niche or ecological role. Niche is an organism's way of life in an ecosystem including habitat, food, competition etc. According to eological species concept, species integrity is maintained by selection to adapt each species to its niche.

2. Biological species concept - It states that a species is agroup of interbreeding natural population and are reproductively isolated from such other groups

3. Phylogenetic species concept - It defines a species as the smallest group of individual on a phylogenetic tree. According to this concept, species is the smallest group that contains all the descendants of a single common ancestor.

4. Morphological species concept - It defines a species by structural features. According to this concept, species is a group of organisms that are similar in appearance and habit to one another. It can be applicable to both sexually and asexually reproducing organisms.
