Chapter 38, Problem 4MCQ
Summary Introduction
Introduction:
Crabs live in the clumps of corals and these crabs protects corals from sea stars. This interaction between crabs and coral is mutualism. In mutualism two different species live together without harming each other and this mutualism is beneficial for both the species.

- What are some conditions that might lead to a mutualistic organism becoming a predator/parasite. Select all that apply. A. Mutualistic nitrogen fixation bacteria might reduce the competitive ability of their host plants in environments with high N availability, because of the energetic costs to the plants of supporting the bacteria B. none of the above C. Mutualistic nitrogen fixing bacteria can become parasites in soil with low nitrogen availability because of the energy costs to the plant of supporting the bacteria D. A mutualist fish species that feeds on ectoparasites of another fish species, might switch to feeding/removing important host tissue or secretions when ectoparasite abundance is too low.arrow_forwardA feeding relationship that proceeds from algae to a fish, then to a fisherman, and then to a shark is _____. a. a food chain b. a food web c. a and barrow_forwardThe figure below shows the growth of two species in two habitats, both when the other species is present and when it is absent.

Commensalism D. Competition E. Parasitismarrow_forward
- Which of the following is not a mutualistic relationship? a. a shark using an aquatic cleaning station b. a helminth feeding from its host c. a bumblebee collecting pollen from a flower d. bacteria living in the gut of humansarrow_forwardWhich 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 levelarrow_forwardCertain plants live in nutrient poor environments and have evolved specialised leaves that attract, trap and digest insects for food. The interaction between the plants and the insects they consume is BEST described as: Select one: a. commensalism. b. parasitism. c. herbivory. d. predation Two related species of African lovebirds exhibit very different ways of carrying nesting materials back to the nest. The Fisher’s lovebird carries nesting material back using its beak, while the peach faced lovebird tucks nesting material in the feathers of its rump. The observation that hybrid lovebirds exhibit intermediate behaviours suggests that nest building behaviour in lovebirds is due to: Select one: a. gene by environment interaction. b. environmental factors. c. genetic factors. d. imprinting.arrow_forward
- According 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.arrow_forwardPlants such as soy, peanuts, and greenbeans have large bacterial colonies growing on their roots that help them retrieve nitrogen from the soil. In return, the bacterial colonies retrieve some nutrients from the plant. What type of interaction is this?

- The brown-headed cowbird is an animal that is native to the Alberta grasslands. Brown-headed cowbirds lay eggs in the nests of other grassland birds, thereby forcing the other species to hatch the eggs and raise the young.The type of symbiotic relationship between the cowbirds and the other species of birds is a. parasitism b. commensalism c. mutualism d. predation Please explain in details why you selected that method.arrow_forwardWhich of the following is the interaction exhibited by the organisms named frog and lizard? a.)mutualism b.)commensalism c.)predation d.)parasitism e.)competitionarrow_forwardAccording 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.arrow_forward
