2. Which field of ecology studies trends and fluctuations in the

and place as a result of birth and death rates and interactions
between predators and prey?

,3. One researcher studies plant cells and how these cells and plants
respond to increased concentrations of carbon dioxide. Another
researcher studies how multiple species interact and what affects
their abundances and distributions. A different researcher studies
a species’ DNA and what changes have occurred between
populations as a result of evolution. What do these researchers all
have in common?
a. They all study community ecology since each researcher is
interested in what happens within communities
b. They are all interested predator-prey interactions
c. They all study one of the many levels of biology with some
application to ecology
d. They all study organismal biology since each researcher
only studies the response of single-celled organisms
ANSWER: C
Difficulty: Medium
Bloom Code: Synthesis
Reference: Section 1.2


4. An ecologist wants to study what plants colonize a site after a
volcano has erupted. She plans to compare what plant species

a. Unnatural history experiment
b. Ecological succession

ANSWER: A
Difficulty: Hard
Bloom Code: Synthesis
