True or false: Density-dependent effects, such as insect population growth rates, can be dramatic.True false question.TrueFalse

True or false? Competition between two different species might affect their rates of population growth.

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.

A deer population has access to abundant but limited resources.  As the size of the deer population increases, how will this growth affect their population density?*2 puntosThe population density remains constantPopulation density increases until resource limit is reachedPopulation density grows indefinitelyPopulation density decreases

What happens to prey density when predator density is high?1 pointIt is constantIt stays the sameIt increasesIt decreaases

Suppose a certain species of insect lives in the lush green canopy of the rain forest. Some of the insects are bright green in color, and some are bright yellow. Assume there is a natural predator of the insect in the area. What do you expect to happen to the populations of the green and the yellow insects over time?  A. The green insect population will increase and the yellow insect population will decrease.  B. The green insect population will decrease and the yellow insect population will increase.  C. Both insect populations will remain constant over time.  D. Both insect populations will increase over time.
