Multiple Choice / Discussion Questions
Additional Questions for Study
- What are biomes? What accounts for the similarities in life
forms found in the same type of biome in geographically
separated areas?
- What challenges are similar for aquatic and terrestrial
biomes? Which challenges are unique to each environment?
- What type of water conservation adaptations are observed in
desert vegetation?
- How does behavior and habitat selection may play a role in
species distribution?
- Untreated sewage entering an oligotrophic lake can cause
eutrophication of the lake. How does this happen?
- As you climb up a mountain, the vegetation changes with
altitude. List some factors that may be causing this change.
- Sunlight does not penetrate into the abyssal zone where deep
sea vent communities are found, so what is the initial source of
energy for these communities?
- A wetland community supports xerophytic / hydrophytic (circle
one) plants.
- How is it possible for many different species to live in the
same habitat without exhausting resources?
- What distinguishes commensalism from mutualism?
- Design a simple experiment to test the competitive exclusion
hypothesis.
- Map out a possible food chain that might exist in a
freshwater lake in Idaho.
- Using glacier retreat as an example, what factors may
contribute to the development of a climax community?
- Why does energy flow through an ecosystem rather than be
recycled in it?
- When is chemical energy produced by photoautotrophs? (be
specific)
- Some of the colder seas away from the tropics are more
productive as primary producers than those in the tropics.
Explain.
- Why do birds and mammals have a low production efficiency?
- Describe the following processes: nitrification;
ammonification; nitrogen fixation.
- You observe mallard ducks in a small pond. Then you notice a
rooster wading out to the ducks with amorous intent. What might
have happened early on in the life of the rooster?
- What is the advantage to dominance hierarchies and
territoriality rather than having everything shared equally in a
population?
- Ducklings eventually ignore a cardboard silhouette of a hawk
that is repeatedly flown over them. What type of behavior is
this?
- Why are many interactions between members of the same
species agonistic?
- How has continental drift historically affected the distribution and
therefore the biodiversity of organisms?
- What does a cladogram represent?
- On a global scale, humans have a higher (secondary)
production efficiency if their diet is (Explain your
answer):
- vegetarian
- omnivorous
- carnivorous
- The EPA asks pregnant women to limit their consumption
of large fish such as tuna, to once per week. The reason for
this decision is that the high mercury content of the
tissues in some of these fish may damage their fetus.
However, it is safe for them to eat other fish such as
sardines, as often as they like. Explain how different fish
living in the same area can have such variation in the
mercury content of their tissues.
