Both the terms population and species differ from each other. They are the two basic levels of classification of organisms in Ecology.
The population is a term used to refer a group of organisms of the same species that live in a particular area. Here, the total number of organisms varies with the time, birth, death, environmental conditions and the dispersion of individuals among other populations. Population helps species to interbreed with each other.
For example-African Elephants, Salmon, The king penguin, etc.

The term species refers to a single individual or a small group of organisms living together with features that are similar and are able to produce offspring successfully. The species may either be a group of plants, animals, birds, reptiles, microbes, and any other living things.
For example- Loxodonta Africana – Elephants, Tursiops truncates- Dolphins, Felis catus –Cat, Quercus douglasii- Blue Oak.
