How do deciduous trees add to the nutrient cycle?
Deciduous trees add nutrients to the soil through leaf litter decomposition.
Deciduous trees do not affect the nutrient cycle in any significant way.
Deciduous trees primarily contribute to the water cycle through transpiration.
Deciduous trees absorb nutrients from the soil without returning them.
Why were wolves absent from Yellowstone from the 1920's to 1995?

Explain why the population of elk built up.
There were just a lot of them and so they reproduced quickly.
There was lots of food for the elk in the park so they reproduced well.
There was no natural predator to hunt them so they became over populated.
No one is actually sure why this happened.
What happened to the vegetation because of the elk population?
The elk ate it all, They reduced the vegetation to almost nothing, or they devoured it, leaving it bare.
Nothing at all. the vegetation just grew as normal.
A drought actually caused the vegetation to die and the elk trampled what was left.
The elk ate some of it but lots of the vegetation remained.

The weather had been much better and the trees grew taller.
The trees did not grow dramatically. Everything stayed the same.
The elk was not there to eat it, and now it can grow.
Grizzly bears compete with elk for berries.
True
False
Which ecological problem was NOT caused by elk?
Few trees were on river banks
Small mammals couldn't hide from predators due to less grass and shrub cover.
Weather patterns changed and there were more severe storms.
Rivers were muddy, making it harder for fish and amphibians to survive.
