Individuals make up a population; populations make up a species; multiple species and their interactions make
up a community
; and multiple species and their interactions make up ecosystems when you include the abiotic factors.
What are populations made up of?
- A population consists of all the organisms of a given species that live in a particular area.
- The statistical study of populations and how they change over time is called demography.
