Species Interactions Quiz

What is mutualism in species interactions?

• A relationship where both species benefit

• A relationship where one species harms another

• A relationship where one species benefits and the other is unaffected

• A relationship where both species are harmed

What does Gause’s principle of competitive exclusion state?

• Two species can coexist if they have identical niches

• Two species cannot coexist if they compete for the same resources

• Two species can coexist if they share resources equally

• Two species cannot coexist if they have different niches

Which of the following is an example of commensalism?

• A bird eating insects off a buffalo

• A lion hunting a zebra

• A bee pollinating a flower

• A remora fish attaching to a shark

What is niche overlap?

• When two species have completely different habitats

• When two species share some of the same resources

• When two species have identical niches

• When two species never interact

What is the difference between intraspecific and interspecific competition?

• Intraspecific competition occurs between different species, while interspecific competition occurs within the same species.

• Intraspecific competition occurs within the same species, while interspecific competition occurs between different species.

• Intraspecific competition involves only plants, while interspecific competition involves only animals.

• Intraspecific competition is always beneficial, while interspecific competition is always harmful.

What does the niche concept refer to in ecology?

• The specific role or position a species has in its environment.

• The physical space a species occupies in a habitat.

• The number of individuals in a species population.

• The genetic diversity within a species.

What is one possible short-term effect of competition between species?

• Increased genetic diversity within a species.

• Local Extinction of one of the competing species.

• Immediate increase in population size.

• Decrease in available resources for all species.

What does coexistence mean in the context of species interactions?

• Two species living in the same area without interacting.

• Two species sharing some aspects of the same resources without one competitively excluding the other.

• One species completely dominating another.

• Two species merging into a single species.

What type of interaction occurs when individuals compete for a resource that limits the survival and reproduction of each species?

• Exploitation

• Positive interaction

• Competition

• Neutral interaction

In which type of interaction does one species benefit by feeding on another species, which is harmed by the interaction?

• Competition

• Exploitation

• Positive interaction

• Neutral interaction
