Science A. The snake population will decrease rapidly and the grass population will increase rapidly. Therefore , A. The snake population will decrease rapidly and the grass population will increase rapidly is correct.
The bar graph shows that the population of rabbits has been severely reduced, from 100% to 51%.
This is because of trapping.
Rabbits are a food source for snakes. With fewer rabbits to eat, the snake population will also decrease.
This is called a top-down effect.
Grass is eaten by rabbits. With fewer rabbits to eat the grass, the grass population will increase.
This is called a bottom-up effect.
The hawk population is not directly affected by the reduction in rabbit population.
However, the hawk population may eventually decrease if the snake population decreases, because snakes are a food source for hawks.
Therefore, the most likely effect of the reduction in rabbit population is that the snake population will decrease rapidly and the grass population will increase rapidly.
The other answer choices are incorrect:
B. The hawk population will increase rapidly and the rabbit population will decrease rapidly.
This is incorrect because the hawk population is not directly affected by the reduction in rabbit population.
C. The grass population will decrease rapidly and the snake population will increase rapidly.
This is incorrect because the grass population will increase, not decrease, with fewer rabbits to eat it.
D. The grass, rabbit, snake, and hawk populations will all decrease rapidly.
This is incorrect because the grass population will increase, not decrease, with fewer rabbits to eat it.
