Question

a population consists of all the individuals of a particular species that live in the same place at the same time. examples of populations include the wolf population in germany in 1800, the red mangrove population in the florida everglades in 2010, and a population of yeast in a lump of dough today.

population growth is the change in the total number of individuals in a population over some period of time. if more individuals join a population than leave it, then population growth is positive. if more individuals leave a population than join it, then population growth is negative. individuals join a population by being born or by immigrating from another population. individuals leave a population by dying or by emigrating to another population.

which equation can be used to calculate population growth?

population growth = ( ) - ( )

Explanation:

Step1: Identify entry factors

Individuals join via births + immigration.
Let entry = births + immigration

Step2: Identify exit factors

Individuals leave via deaths + emigration.
Let exit = deaths + emigration

Step3: Define population growth

Growth = entry - exit
$ \text{population growth} = (\text{births} + \text{immigration}) - (\text{deaths} + \text{emigration}) $

Answer:

$\text{population growth} = (\text{births} + \text{immigration}) - (\text{deaths} + \text{emigration})$
