These penguins are all members of the species Aptenodytes patagonicus. What is the difference between a species and a population
Vikki [24]

Answer:

A species refers to the group of similar organisms that can interbreed to produce a viable offspring. For example, <em>Homo sapiens </em>is a species of humans, <em>Panthera leo </em>refers to the species of lions et cetera.

In contrast, a population in ecology refers to the group of organisms of the same species living in a particular area. For example, the deer population in a forest, human population in a town et cetera.

For example, <em>Aptenodytes patagonicus </em>refers to a species of penguins but number of penguins of the same species living in a particular area would make up a penguin population of that area.
