Concept explainers
(a)
To identify: The species concept(s) that can be applied to sexual and asexual species both.
Concept introduction:
The word “species” has been defined differently on the basis of three main species concepts namely; “Biological Species Concept”, “Morphological species Concept”, and “Ecological Species Concept”. According to the “Biological species concept”, a group of population with interbreeding members to produce viable fertile offspring is called species. Human beings are one of the best examples of biological species concept as they belong to the same species. In the “morphological species concept”, the species can be differentiated by their body shapes and other structural features whereas; in the “ecological species concept” the species can be defined by their ecological niche.
(b)
To explain: The most useful concept to identify species in the field.

- magine that you are conducting research on fruit type and seed dispersal. You submitted a paper to a peer-reviewed journal that addresses the factors that impact fruit type and seed dispersal mechanisms in plants of Central America. The editor of the journal communicates that your paper may be published if you make ‘minor revisions’ to the document. Describe two characteristics that you would expect in seeds that are dispersed by the wind. Contrast this with what you would expect for seeds that are gathered, buried or eaten by animals, and explain why they are different. (Editor’s note: Providing this information in your discussion will help readers to consider the significance of the research).arrow_forwardWhat is the difference between Uniporters, Symporters and Antiporters?
