Which of the following statements is consistent with the principle of competitive exclusion? Bird species generally do not compete for nesting sites Two species with the same fundamental niche will likely exclude all other species Natural selection tends to increase competition between closely related species When two species are in direct competition for the same resource, one species will eventually prevail

The competitive exclusion principle is best defined as Multiple Choice the competition among individuals of the same species in the same location. the principle that two species that occupy the same niche cannot coexist indefinitely. an interaction between species that enhances the fitness of the exploiting individual while reducing the fitness of the exploited individual. the principle that if an organism allocates energy to one function, such as growth or reproduction, it reduces the amount of energy available to other functions.
An ecologist studying several forest-dwelling, insect-eating bird species does not find any evidence of interspecific competition. The most likely explanation is (a) lack of a keystone species (b) low species richness (c) pronounced intraspecific competition (d) coevolution of predatorprey strategies (e) resource partitioning
Figure 45.10b If the major food source of the seals declines due to pollution or overfishing, which of the following would likely occur? The carrying capacity of seals would decrease, as would the seal population. The carrying capacity of seals would decrease, but the seal population would remain the same. The number of seal deaths would increase but the number of births would also increase, so the population size would remain the same. The carrying capacity of seals would remain the same, but the population of seals would decrease.
Figure 19.6 If the major food source of seals declines due to pollution or overfishing, which of the following would likely occur? a. The carrying capacity of seals would decrease, as would the seal population. b. The carrying capacity of seals would decrease, but the seal population would remain the same. c. The number of seal deaths would increase, but the number of births would also increase, so the population size would remain the same. d. The carrying capacity of seals would remain the same, but the population of seals would decrease.
When r is a positive number, the population size is (a) stable (b) increasing (c) decreasing (d) either increasing or decreasing, depending on interference competition (e) either increasing or stable, depending on whether the species is semelparous
According to the competitive exclusion principle, two species cannot exist together if they occupy the same niche. Either they diverge their niches so they can coexist or one species will die out.All of the following are consistent with the principle of competitive exclusion EXCEPT Select one: a. Birds and bats both consume flying insects, but birds are active in the day and bats are active at night. b. Two species that share the same niche will exclude other competing species. c. Different bird species forage for insects in different parts of the same tree. d. When two species of Paramecium are grown in the same medium, one strain will eventually eliminate its competitor.
What term is used to describe how members of different species strategize how, when, and where they will obtain resources to reduce competition? competitive reduction resource partitioning interspecies competition intraspecies competition
Which of the following statements is correct regarding the competitive exclusion concept? a. multiple species can’t share the exact same niche within a community b. the realized niche of a species is different from its fundamental niche. c. competition within a population results in the success of the best-adapted individuals. d. two species cannot coexist within the same habitat.
Which of the following conditions tend to destabilize populations (e.g. make extinctions more likely) for a predator and prey demonstrating Lotka-Volterra predator-prey dynamics? More than one food source (prey species) for the predator No immigration or emigration of the predator and prey The existence of prey refuges why option B is correct?
The Atlantic cod population is of primary economic importance to fishingcommunities throughout the maritime provinces in Canada. Unfortunately, thispopulation has underwent an extreme collapse in recent years due to overfishing.Some argue, however, that the collapse of the cod population may actually beattributed to an increase in the population of harp seals, a known predator ofcod. One suggestion to help cod stocks recover is therefore to permit the huntingof harp seals on a large scale. Suggest and explain one potentially negativeconsequence of limiting the harp seal population.
A gypsy moth population has overtaken a grove of oak trees. The gypsy moths eat the trees, causing the trees to die. What type of density-dependent factor would the gypsy moths be considered? predation disease and parasites competition physiological change
When Charles Darwin discovered the various finch species on the Galápagos islands, he was surprised to find so many different but related species in such a small geographic area. Which of the following best illustrates the correlation between competitive advantage and an individual’s traits in a particular environment? Different islands had very different food resources available, and only individuals that were adapted to eat those food resources survived and reproduced on that island. Finches had no natural predators on the island before Darwin’s voyage, allowing them to prosper on the islands. Competition between different species for food resources led to resource partitioning of the ecosystem. Mating behaviors in finch species ensure that different species of finch will not interbreed with one another.
