If a population for a certain organism is above the carrying capacity of an ecosystem, which of the following is a plausible outcome?

• the population will continue to grow because they will start migrating to other ecosystems

• the population will decline, as there is a limited number of resources in the ecosystem

• the population will decline because there will be an increase in predators

• the population will continue to grow until biotic potential is reached

The image (on the right) is a population graph from the predator-prey game. Green indicates grass, blue indicates rabbits, and red indicates wolves. The rapid growth in grass shown at the right of the graph is probably due to

• rabbits becoming extinct

• wolves controlling the rabbit population

• rabbits going on diets

• wolves becoming extinct
