Edited by Tayyaba Rehman — By Fiza Rafique — Updated on November 2, 2023
Species are a group of living organisms capable of interbreeding, while a population is a group of individuals of the same species living in a particular area.

Key Differences
A species is a fundamental category in the classification of living organisms, referring to a group whose members share common attributes and can interbreed to produce fertile offspring. Populations, however, represent a group of individuals of the same species that inhabit a common geographical area and are capable of interbreeding.
While species is a biological concept used to categorize living organisms based on shared characteristics and genetic similarity, population focuses more on the group dynamics of a species in a specific environment, such as their numbers, density, and genetic composition.
Species exist as distinct entities that are theoretically capable of interbreeding regardless of their global distribution, whereas populations are context-specific, representing a localized subset of a species. For instance, all humans belong to the species Homo sapiens, but a population would refer to the people living in New York City.
Conservation efforts often focus on species to preserve biodiversity, ensuring that the genetic material and unique adaptations of different species are maintained. In contrast, ecologists might study populations to understand how environmental factors affect the survival and reproduction of a species in a particular area.
The concept of a species is integral to understanding the diversity of life and is used in taxonomic classification to group similar organisms together. A population, by contrast, is a more dynamic concept, changing with births, deaths, migrations, and variations in individual health and reproductive status within a specific region.

Species

A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction.

Population
In biology, a population is a number of all the organisms of the same group or species who live in a particular geographical area and are capable of interbreeding. The area of a sexual population is the area where inter-breeding is possible between any pair within the area and more probable than cross-breeding with individuals from other areas.In sociology, population refers to a collection of humans.
