35 | Ecology and the Biosphere 845




35 | ECOLOGY AND THE BIOSPHERE
REVIEW QUESTIONS
1 C, H, O, and N are nutrients that cycle through Earth in different forms. Which level of
ecology includes the study of nutrient cycling though the environment?
A Organismal ecology
B Population ecology
C Community ecology
D Ecosystem ecology
Solution The solution is (D). Ecosystem ecology is the study of interactions of abiotic (nutrient
cycling) and biotic factors.
2 What is arranged from least inclusive to most inclusive?
A Population > ecosystem > community > biosphere
B Ecosystem < population < biosphere < community
C Biosphere < ecosystem < community < population
D Population < community < ecosystem < biosphere
Solution The solution is (D). Biosphere includes all of the other levels of biological
organization in a sequential order. Populations form a community, a community is
part of the ecosystem, and the biosphere includes population, community, and
ecosystem.
3 An ecologist is studying the ways that patterns on the wings of an endangered butterfly
species allow it to escape predators such as birds. This is an example of —
A mimicry
B organismal ecology
C mutualism
D community ecology
Solution The solution is (B). Organismal ecology is a study of a particular type of organism,
such as the butterfly in this case.
4 Each year, Lake Michigan beach visitors are warned of possible exposure to E. coli, which
can cause illness. To understand how both biotic and abiotic environmental conditions
affect the risk of E. coli abundance, which type of individual should an infectious disease
specialist collaborate with?
A An ecosystem ecologist
B A podiatrist

846 35 | Ecology and the Biosphere


C A community ecologist
D A population ecologist
Solution The solution is (A). He would collaborate with an ecosystem ecologist, who studies
the interaction of biotic and abiotic factors.
5 Some bacterial species can use nitrogen directly from the atmosphere. In their ecosystem,
the bacteria are a(n) —
A biotic factor
B abiotic factor
C infectious factor
D symbiotic partner
Solution The solution is (A). Bacterial species are living, so they are biotic factors.
6 Photosynthetic organisms are important to most ecosystems because they —
A synthesize organic compounds that they obtain from decaying heterotrophs
B can use carbon dioxide and sunlight and synthesize their own food
C use wind energy to synthesize organic compounds
D synthesize inorganic compounds from organic compounds
Solution The solution is (B). Plants are primary producers and use carbon dioxide and sunlight
to synthesize glucose.
7 What does study of population ecology focus on?
A The number of individuals of one species in an area and how and why that number
changes over time
B The processes driving interactions within and among different species within an area
C The adaptations that enable individuals to live in specific habitats
D Plants and animals living in an enclosed area
Solution The solution is (A). Population ecology focuses on a population, a group of
interbreeding organisms living in the same area at the same time.
8 The study of the effect of abiotic factors such as rain and temperature on the distribution
of living organisms is known as —
A community ecology
B biogeography
C ecosystem
D geography

35 | Ecology and the Biosphere 847


Solution The solution is (B). Biogeography is the study of how abiotic factors such as rainfall
and temperature affect the flora and fauna of a region.
9 Individuals within a single species of pine tree are often found in different geographical
locations in North America and Canada. Why?
A They were not separated geographically over millions of years and did not evolve to
become different species.
B Plant breeders carried seeds to different areas.
C Pollen from pine trees traveled to distant locations.
D Pine tree species were present widely and died out in some areas.
Solution The solution is (A). Pine trees were not separated geographically and did not evolve
to be different species.
10 An ecologist hiking up a mountain may notice different biomes along the way due to
changes in all of the following except —
A elevation
B rainfall
C latitude
D temperature
Solution The solution is (C). Latitude remains the same as the ecologist climbs up the
mountain.
11 Temperate forests have plants of varying sizes. In this particular environment, understory
plants in a temperate forest are notable for adaptations to capture limited —
A water
B nutrients
C heat
D sunlight
Solution The solution is (D). Sunlight is a limiting factor because understory plants are
covered with a canopy.
12 Which body of water lacks temperature stratification?
A Estuaries
B Lakes
C Seas
D Oceans
Solution The solution is (A). Temperature stratification does not take place in estuaries.
