- Although a species might be physiologically able to live under a wide range of resource conditions, competitors may restrict its use of resources in a particular location. This is known as a character displacement. b mutualism. c realized niche. d fundamental niche. e interference competition.Which of the following defines the role of a species in a community,including its habitat and interaction with other species?a. ecological nicheb. competitive exclusionc. competition leveld. mimicrye. None of these are correctbWhich of the following defines the role of a species in a community,including its habitat and interaction with other species?a. ecological niche d. mimicryb. competitive exclusion e. None of these are correct.c. competition level
- How can a commensalism become a mutualism? a. A commensalism cannot become a mutualism. b. An interaction that was once harmful to one species becomes beneficial to both species. c. An interaction that was once harmful to both species becomes beneficial to one species. d. An interaction that was once beneficial to both species becomes beneficial to only one species. e. An interaction that was once beneficial to one species becomes beneficial to both species.Which of the following relationships is least likely to result in coevolution? O A. Mutualism O B. Host-parasite O C. Amensalism O D. Predator-prey O E. Competition Moving to another question will save this response.Read this quote from Charles Darwin (from Origin of Species). What is he describing? "Thus, I can understand how a flower and a bee might slowly become, either simultaneously or one after the other, modified and adapted to each other in the most perfect manner, by the continued preservation of all the individuals which presented slight deviations of structure mutually favorable to one another." An interaction network. A predator/prey cycle. O Coevolution. An obligate mutualism.

AmensalismAccording to the competitive exclusion principle,a. one species is always more competitive than another for a particular food source.b. competition excludes multiple species from using the same food source.c. no two species can occupy the same niche at the same time.d. competition limits the reproductive capacity of species.The association which involves the exchange of nutrients between two species is referred to as: -commensalism -mutualism -predation -antagonsim
- Akeystone species is one:a.that makes up a very large proportion of total community biomass.b.that feeds on a very large fraction of all available prey species.c.that is fed on by a very large fraction of all predators in itscommunity.d. whose feeding activities have adisproportionate effect on the structure of its community.e.that occupies the lowest level (the base) of the food web.Marie studies how resource competition influences the coexistence of two predators. Marie studies ecology at the biological level of organization of the ... a. Ecosystem O b. Community O c. Food web O d.
