What is the difference between a species and a population?What is the difference between a species and a population?
WITCHER [35]

Answer:

A population is a group of organisms of the same species, in the same place

I like to remember it with humans.

Humans (homo sapiens) are a species. We are all genetically similar and can share genetic material by reproduction.

In a city, a lot of humans are together and that is a population of humans

As a species however, we are all over the place

A first-hand source such as an experiment is called a primary source. 

A primary source is where you can share new information or report on what you have discovered. Some primary sources are research data, interviews, audio recordings, and autobiographies.

A secondary source is where you describe and discuss about the primary sources. They are used to collect and gather primary source information. Some secondary sources are textbooks, review articles, and scholarly books.

A tertiary source is a source about summaries. A tertiary source can be used to look up information or get an overview about what it is you are wanting to know. Some tertiary sources are dictionaries, handbooks, encyclopedias, Wikipedia, and guidebooks.
