Answer 2

Explanation:

#1) To lower the price of oil and reduce dependence on foreign imports,

a federal government is debating whether to open large stretches of its coastline to domestic drilling. Evaluate this plan in terms of two ecosystem services that the county might gain and two services the country might lose if the coastline is opened for drilling. Be sure to explain how a perceived negative externality might become an internal cost.

#2) A common student misconception is that plants photosynthesize only during the day and conduct cellular respiration only at night. In what way is this statement inaccurate. Describe an accurate relationship between photosynthesis and cellular respiration.

#3) A friend argues that foodchains can continue

indefinitely, so that the energy originally entered the

system as sunlight is passed from consumer to consumer without ever needing to be replenished. Explain why this statement is inconsistent with the second law of thermodynamics and therefore incorrect. Be sure to include in your response an accurate description of how energy passes from organism to organism in a food chain.

#4) You decide to halve your time spent in the shower each day and to turn off the water while you're brushing your teeth and washing your face at the sink. Evaluate the effect that these actions could have on 2 different aspects of the water cycle if every person in your neighborhood performed them.

# 5) For many generations, a lake has been home to a single species of mussel; these mussels help clean the lake by filtering out plankton and other microscopic organisms. One year, humans living in the area accidentally introduce a new species of mussel to the lake. This new species has the same diet as the old species. Predict what will most likely result from these 2 species.

#5) Predict how the population levels of a predetor and prey with carrying balance would change in an ecosystem in which the average predator was 1/3rd more successful in capturing its prey. How would this change be reflected in a graph

#6)Consider a species of trout that lives in a river that has been divided by an impassable dam. The dam creates two distinct populations of trout, one on either side. A classmate argues that both populations will evolve along the same lines. Is this classmate right? Evaluate her statement in terms of the effect the dam will likely have on gene flow. Be sure to discuss the role of natural selection as well.

#7) As a result of logging and other human-induced causes of deforestation in its habitat, a species of fox has experienced a sufficient decline in its population to be protected under the Endangered Species Act. Outline a plan that includes at least three different steps to restore the fox population to levels that would no longer require protection.

#8) The plans for several new housing developments call for a large forest to be divided into four distinct sections, each of which is seperated from the other sections by networks of buildings, backyards, and major roads. Describe the effects that these plans, if implemented, would likely have on the population of deer living in the forest. In addition, please describe how the plans would likely affect the trees and other vegetation growinfg along the edges of the resulting sections.
