Create a food web using the descriptions of the following organisms: (Don't forget the ARROW points to where the energy flows to!)

a. RABBITS eat GRASS and berries from BERRY BUSHES.
b. WOLVES eat rabbits and ground hogs.
c. GROUNDHOGS eat berries and grass.
d. BEARS eat berries and deer.
e. DEER eat grass.
* Do not forget the SUN!

1

If there is a disease that kills most of the berry bushes, which population of organisms is likely to be affected? How will they be affected and why?

2

In the food web above, if we were to introduce another predator that eats groundhogs and rabbits, what is likely to happen to the wolf population? Why? (select two)

Which TWO would go here in the middle of this energy pyramid?

Which would go here at the top of this energy pyramid?

1

Which amount of energy would be at the bottom?

1

Which amount of energy would be in the middle? (Hint: only 10% of energy is transferred from level below it.)

1

Which amount of energy would be at the top? (Hint: only 10% of energy is transferred from level below it.)

Which trophic level would you call the middle?

Why are there more herbivores in an ecosystem than carnivores?

1

What happens to the energy that is "lost" at each trophic level?

Why is the disappearance of grass more devastating to the community than the disappearance of hawks? (If the grass goes away, why is that worse than if the hawks go away?)
