Define the following terms related to species interactions.
Why are trees important to an ecosystem, even after they have fallen?
Provide a habitat for
wildlife, and decompose, releasing nutrients into the soil.
How does the second law of thermodynamics relate to energy moving up trophic
The second law of thermodynamics says that potential energy decreases as
energy is transferred between s
ystems. This means that as energy is transferred
from one organism to another (i.e. a primary producer to an herbivore),
potential energy decreases or is lost to respiration and waste.
Using the food web above, w
results from removing a primary
consumer, such as a deer or moose from the ecosystem?
The wolf population will decrease significantly or collapse.

Match the following terms with their definitions.
National wildlife refuges
National wilderness preservation areas
National resource lands
Wilderness, scenic view and unusual landforms that have distinct boundaries,
and are preserved for the enjoyment of the US public __
Areas that are set aside for the primary purpose of protecting wildlife, such as the
endangered Marbled Murrelet. ___
Publically owned lands usually formed within national forests or rangelands,
which limit human use to preserve the ecosystem, by
prohibiting logging, mining
or construction of roads. __
Along with National Rangelands (for grazing) these areas are managed by the
National Forest Service, these are section of land dominated by woody plants
thin Publically owned lands. __
hese areas of land are managed by the bureau of land, which are set aside
for resources accessed by the public. Publically owned oil rigs are an example
of this type of land. _

What is an example of wetland mitigation? Why is wetland mitigation
An example of wetland mitigation is building an apartment complex on top of
a wetland and then
building a wetland along a highway on unused land.
disadvantage to this is that building where there is supposed to be a wetland,
can lead to pest problems and land saturation problems. The problem with
building a wetland where there was never a wetlan

an ecosystem where one does not exist originally involves a lot of
components that have to be synthetically implemented, and can be easily

Explain how Dissolved Oxygen, Nitrate, phosphate could be used to identify whether
a water system is contaminated.
If dissolved oxygen levels are low, that may indicate that BOD is high due to
increased decomposition of sewage or agricultural runoff, or runoff from cattle farms.
If nitrate levels and phosphate levels are high that might also indicate the present of
icultural or sewage run off.
