K-selected species:Question 17Select one:a.are adapted to stable environments.b.population growth is controlled by density-independent factors.c.have the potential for rapid population growth.d.usually have a population size well below the carrying capacity.

Explain the difference between r-selected and K-selected species.

As N (population size) approaches K (carrying capacity) for a certain population, which ofthe following is predicted by the logistic equation?a) The growth rate will not change.b) The growth rate will approach zero.c) The population will increase exponentially.d) The carrying capacity of the environment will increase.

Populations are capable of different speeds of growth depending on whether or not they have a carrying capacity. A carrying capacity refers to a limit on the growth of the population. These limits may involve the amount of food, water, space, or shelter in a location. When a population has a carrying capacity, the growth is represented by a logarithmic model, shown below.Population Ecology Growth Graph by Mathboy321 (CC BY-SA 4.0)Which of the following carrying capacity factors is considered density-independent?Elimination ToolSelect one answerAFood.BNatural disasters.CWater.DShelter.

The maximum growth rate characteristic of a species is called its __________.Question 8Select one:a.limitb.carrying capacityc.biotic potentiald.exponential growth pattern

Select whether each statement refers to a density-dependent or density-independent factor for population growth.When a prey species becomes more common, predators can more easily find it and kill relatively more. This would be a factor that limits population growth.A hurricane would be a factor that would impact population size.A limit to population growth that has greater influence as population size increases such as a parasite that can more easily jump from host to host would be a factor.
