- Which of the following is least likely a result of competition? Increase in carrying capacity for both species Character displacement (populations possess different traits in the presence of similar species) Reduced niche breadth (smaller realized than fundamental niche) Resource partitioningThe graph below shows the species richness of a community undergoing secondary succession. The letters R, S, T, and U identify four distinct seres. Answer the questions by identifying the correct sere. Seres can be used as an answer once, more than once, or not at all. Number of Species R 20 V Time S Which sere is dominated by r-selected species? R Which sere is the climax stage? S T U Which sere shows the EFFECT of strong competition? TScientists compared the timing of fruit foraging for two different species of lemurs in Madagascar. They found that each species foraged within a 4 hour window of time Species 1 forages during the day and Species 2 forages at night. What direct advantage does having different foraging times give these lemur species? O A. Species 1 can outcompete Species 2 resulting in competitive exclusion O B. Species 2 can outcompete Species 1 resulting in competītive exclusion O C. Reduced competition for both species through resource partitioning O D. Improved seed dispersal for the plant species

- When Charles Darwin discovered the various fish species on the Galapagos 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 in an individual streets in a particular environmentThe 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.Two fish species, Species 1 and Species 2 live in the same lake at the same time and are competing for the same prey. Which of the following is/are a possible outcome of competition? Select all that apply O Species 1 is better at obtaining prey than Species 2 and drives Species 2 to extinction in the habitat. Species 2 is better at obtaining prey than Species 1 and drives Species 1 to extinction in the habitat. O Species 1 begins to forage for prey in the shallow portions of the lake, while Species 2 forages in the deeper parts of the lake, and both species persist in the habitat.

- 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.In exploitative interactions, one species gains a fitness advantage at the cost of another species. Which of the following is an example of exploitation? O A squirrel uses a hole in a tree as shelter A large grouper fish is cleaned of parasites by a cleaner shrimp O A millipede feeds on dead fragments of plants and animal feces OA dragonfly kills and eats a beetle Algae grows inside the tissue of a coral and produces nutrients for bothWhat is accurate about the nature of competition between species? Choose All That Apply O it takes energy away from other functions of the organisms involved Otraits that reduce competition are generally selected for it is less intense the more the niches overlap overtime it could potentially result in resource partitioning
