- As used in the interaction grid, MUTUALISMS are: Plus/plus interactions between two different species. Plus/plus interactions between two individuals of the same species. Plus/plus interactions either within or between species. Any interaction that is plus for one or both species.The relationship between impalas and oxpeckers, the birds that feed on their ticks, is an example of a mutualism, not commensalism, because one species benefits and the other is not helped or harmed neither species benefits both species are harmed one species benefits but the other is harmed both species benefit, not just oneSpecies within a community interact with each other in a variety of ways. Match each scenario with the type of species interaction it describes. Competition Commensalism Consumption Mutualism grass and clover both using the mice eating seeds lizards catching insects for food limited nutrients in the same patch of soil from sunflowers Answer Bank orchids growing harmlessly on branches of trees bees receiving nectar in exchange for pollinating flowers doves and cardinals eating seeds from the same limited number of plants
- Describe two interspecific interactions where both species benefit and both species are at a disadvantage. Identify the interaction.Which of the following describes Mullerian mimicry? Group of answer choices Mullerian mimicry is a dishonest signal where 2 or more species share warning coloration. Mullerian mimicry is an honest signal where 2 or more species share warning coloration. Mullerian mimicry is an honest signal where 2 or more species share parasites. Mullerian mimicry is a way that 2 or more species hide from predators.Which of the following ecological situations would result in INCREASED selection on the peaceful “dove” strategy relative to the hawk-dove game discussed in class? Increased value of the resource Unlikely that the individual will have future opportunities to get the resource Decreased cost of displaying All of the above
- In which type of species interaction do both species have lower success when the other species is present? Group of answer choices mutualism commensalism competition predationWhich of the following do NOT represent examples of interactions within communities? * Defence mechanisms AND intraspecific competition interspecific competition defense mechanisms defence mechanisms AND interspecific competition intraspecific competitionSpecies that are good biological indicators often respond to environmental changes more rapidly than other species. True False
