Natural Selection

A population can be described by:

• the traits present

• the number of individuals who have each trait

• the different species of organisms in it

• abiotic factors

Answer explanation

A population only has ONE kind of organism (species). Each organism of that population can have different traits. For example, a population of betta fish can have many different colors (traits).
