Multiple Choice

Multiple Choice

In the stable food chain shown below, what would you expect to happen initially if you were to suddenly double the population of rabbits?

• The populations of the other three species would also increase.

• The populations of the other three species would decrease.

• The grass population would decrease. The snake population and hawk population would increase.

• The grass population and hawk population would decrease. The snake population would increase.

Multiple Choice

Multiple Choice

Trapping has severely reduced the population of rabbits in an ecosystem, as shown in the bar graph below. What is the most likely effect this will have on other organisms?

• The snake population will decrease rapidly and the grass population will increase rapidly.

• The hawk population will increase rapidly and the rabbit population will decrease rapidly.

• The grass population will decrease rapidly and the snake population will increase rapidly.

• The grass, rabbit, snake, and hawk populations will all decrease rapidly.
