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
It refers to the maximum capacity of an ecosystem to sustain a population of organisms without deteriorating.

Use of Pesticides
Populations can grow indefinitely.
TRUE
FALSE
Which of the following statements describes density-independent limiting factors?
Competition is an example.
Parasitism and disease are examples.
Environmental extremes, such as a hurricane or drought, are examples.
Their effects increase as the population increases in an area.
A scientist is developing a computer model to determine the maximum population size, or (a) , of eagles and other birds of prey in a forest ecosystem. The model should represent all of the (b) that affect the populations.
limiting factors
limiting population
immigration factors
carrying capacity
On Isle Royale, wolves are the main predators of moose. The graph shows the changing wolf and moose populations on the island over a 50-year time span. Which statement provides the strongest explanation for the trends in the two populations?
The populations of predators and prey are limited by abiotic factors only.
Predation acts a density-dependent limiting factor on prey, but not on predators.
Predation acts as a density-independent limiting factor on predators, but not on prey.
Predator-prey relationships act as density-dependent limiting factors on both predators and prey.
A population of mountain lions lives in an alpine forest. As the population increases, which of these events becomes more likely to occur?
Female mountain lions raise an increasing number of pups per litter, and a greater percentage of pups survive to adulthood.
Competition for territory and other resources acts to slow the growth rate of the population.
A wildfire, drought, or other natural disaster acts to decrease the mountain lion population by at least 50 percent.
A decrease in competition acts to increase the growth rate of the population.
