CHAPTER 54 PRACTICE TEST EXAM
WITH CORRECT QUESTIONS AND
ANSWERS 2025
1) Which of the following statements is consistent with the principle of competitive
exclusion?
A) Bird species generally do not compete for nesting sites.
B) The random distribution of one competing species will have a positive impact on the
population growth of the other competing species.
C) Two species with the same fundamental niche will exclude other competing species.
D) Even a slight reproductive advantage will eventually lead to the elimination of the
less well adapted of two competing species.
E) Natural selection tends to increase competition between related species. -
CORRECT-ANSWERSAnswer: D
Topic: Concept 54.1
Skill: Application/Analysis
2) According to the competitive exclusion principle, two species cannot continue to
occupy the same
A) habitat.
B) niche.
C) territory.
D) range.
,E) biome. - CORRECT-ANSWERSAnswer: B
Topic: Concept 54.1
Skill: Knowledge/Comprehension
3) Which of the following best describes resource partitioning?
A) competitive exclusion that results in the success of the superior species
B) slight variations in niche that allow similar species to coexist
C) two species that can coevolve to share identical niches
D) differential resource utilization that results in a decrease in community species
diversity
E) a climax community that is reached when no new niches are available - CORRECT-
ANSWERSAnswer: B
Topic: Concept 54.1
Skill: Knowledge/Comprehension
4) As you study two closely related predatory insect species, the two-spot and the three-
spot avenger beetles, you notice that each species seeks prey at dawn in areas without
the other species. However, where their ranges overlap, the two-spot avenger beetle
hunts at night and the three-spot hunts in the morning. When you bring them into the
laboratory and isolate the two different species, you discover that the offspring of both
species are found to be nocturnal. You have discovered an example of
A) mutualism.
B) character displacement.
, C) Batesian mimicry.
D) facultative commensalism.
E) resource partitioning. - CORRECT-ANSWERSAnswer: E
Topic: Concept 54.1
Skill: Synthesis/Evaluation
5) Resource partitioning would be most likely to occur between
A) sympatric populations of a predator and its prey.
B) sympatric populations of species with similar ecological niches.
C) sympatric populations of a flowering plant and its specialized insect pollinator.
D) allopatric populations of the same animal species.
E) allopatric populations of species with similar ecological niches. - CORRECT-
ANSWERSAnswer: B
Topic: Concept 54.1
6) Which of the following is an example of cryptic coloration?
A) bands on a coral snake
B) brown or gray color of tree bark
C) markings of a viceroy butterfly's wings
D) colors of an insect-pollinated flower's petals
E) a "walking stick" insect that resembles a twig - CORRECT-ANSWERSAnswer: E
