7. Which of the following systems is composed of assemblages of organisms together with their
physical and chemical environments?
a. Organism
b. Population
c. Community
d. Ecosystem
ANSWER: d
8. An ecologist who studies populations would most likely be
interested in
a. Adaptations that help individual organisms live in their
environment.
b. Births and deaths of individuals belonging to a particular species in a particular place.
c. The number and relative abundance of species living in a particular place.
d. Physical and chemical transformations of energy and materials in the soil, atmosphere, and
water.
ANSWER: b
9. Explain how studying a community can provide insight into population changes.
ANSWER: Many species’ interactions play a part in birth and death rates of populations, such as
any species that relies on another for food. Understanding these relationships is often
essential to understand why a population is growing or shrinking.
10. Explain how the definition of species has become more complicated. Give an example.
ANSWER: While species were originally defined as organisms that could interbreed and produce
fertile offspring, exceptions continue to be found. For example, prokaryotic organisms
can transfer DNA to each other in horizontal gene transfer. This makes it hard to have a
clear difference between species, since they can easily share DNA but are varied enough
that they cannot be considered one species.
11. The first law of thermodynamics states that
a. Life requires energy to be continually added to Earth.
b. Matter cannot be created or destroyed.
c. When energy changes form, some energy is lost.
d. Energy cannot be created or destroyed, but only change form.
ANSWER: d
12. In a dynamic steady state
a. There are no inputs or outputs to the system.
b. The second law of thermodynamics does not apply.
c. There is no net change in the system.
d. The system will continue to grow.
