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

I saw the food pyramid that accompanied this problem. Lowest is the grass, followed by rabbits, then snakes, last is the hawk.

These are the choices of the above question.

A. The snake population will decrease rapidly and the grass population will increase rapidly. B. The hawk population will increase rapidly and the rabbit population will decrease rapidly. C. The grass population will decrease rapidly, and the snake population will increase rapidly. D. The grass, rabbit, snake, and hawk populations will all decrease rapidly.

The correct answer is: A. The snake population will decrease rapidly and the grass population will increase rapidly.

With the absence of rabbits, grass growth will become unmanageable and because rabbits is their food source, snakes will die due to starvation.

The effect it will have on other organisms is the organisms that eat rabbits will have to find another food source and finding food will be more competitive. The organisms (plants) that the rabbit eats will become overpopulated.
