population density =

• $\frac{n.\ organisms}{area}$

• $n.\ organisms\ \times\ area$

• $\frac{tot.biomass}{area}$

• $\frac{tot.\ energy}{n.\ organisms}$

growth rate =

• $birth.rate\ -death.rate\ +\ migration$

• $\ \frac{birth.rate}{death.rate}+migration$

• $population.size\ \times\left(birth.rate-death.rate\right)$

• $\frac{population.size}{birth.rate\ -death.rate}$
