What change is likely to occur in a population of beetles that suddenly faces predation from an invasive species of frogs? A. The beetles' survivorship curve will change type. B. The beetles' minimal viable population will decrease. C. The carrying capacity of beetles will increase. D. The population density of beetles will decrease.

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.

Natural selection can operate on predator populations as well as on prey. Suppose that over time trees became covered in lichen and the proportion of light moths increased to nearly 100%. What is the most likely consequence for predator populations?  A. Bird populations will decrease, at least for a while.  B. Over time, birds with better eyesight will become more common.  C. Birds may change hunting strategies or seek other sources of food.  D. All of the above.

During periods of rapid environmental change, what may happen to a species that was well-suited to the former environment?Group of answer choicesTraits that were favorable in the original environment may be detrimental in the new environment.Individuals with particular traits that provide an advantage in the new environment will have higher reproductive success.The population may change so much in adapting to the new environment that it is considered a new species.A, B. C and D are correct

Which of the following statements best describes what will most likely occur to the moth populations in the image below?  A. The light moths will be captured by predators more easily than the dark moths, and the population of dark moths will rise.  B. The light moths will be captured by predators more easily than the dark moths, and the population of light moths will rise.  C. The dark moths will be captured by predators more easily than the light moths, and the dark moths will probably go extinct.  D. The light moths will change their wing color to match that of the dark moths.

In a population of beetles, there are two color morphs: green and brown. The green beetles are more easily seen by predators on the forest floor, while the brown beetles blend in with the environment. Over several generations, the proportion of brown beetles in the population increases, while the proportion of green beetles decreases.Question 10Answera.Natural Selectionb.Genetic Driftc.Gene Flowd.Mutation
