Imagine a group of hunters kills half of the rabbit population. How will it affect the other organisms?no

If half the rabbits in a given population are killed off,
there will be impacts both up and down the food
chain.

Looking down the food chain, the things that the
rabbits eat will not be eaten as much.  Therefore, their population will increase.  They
may crowd out other plants that compete for their niche (if the rabbits didn't eat those
too).

Other organisms that eat the same things as rabbits
will also flourish.  They will have less competition for the
food.

Up the food chain, animals that depend on the rabbits
for food will see their populations drop.  This is because they will not have as much
food to eat.
