What effect can competition have on a population size?

• Competition can result in one population decreasing

  while another increases.

• Competition between species rarely affects the

  population size of either species.

• Competition happens when one species preys upon

  another.

• Species in one habitat or location can greatly impact

  the same species in a different habitat or location.

What patterns do scientists usually observe between predator-prey relationships?

• The predator population is typically larger than the prey

  population.

• hen the prey population increases, the predator population

  decreases at the same time.

• When the prey population decreases, the predator population

  also decreases within a short time period later.

• There is no relationship between the populations of predators

  and prey.
