The graph shows the variation in the population size of finches living on one of the Galápagos Islands.The finches' only food source is seeds found on the island. The seed abundance on the island during the same time period is shown.What explanation can be constructed based on the evidence in the two graphs?A Higher seed abundance results in a lower population size of finches.B Lower seed abundance results in a greater population size of finches.C Higher seed abundance results in a greater population size of finches.D Changes in seed abundance do not affect the population size of finches.
Question
The graph shows the variation in the population size of finches living on one of the Galápagos Islands.The finches' only food source is seeds found on the island. The seed abundance on the island during the same time period is shown.What explanation can be constructed based on the evidence in the two graphs?A Higher seed abundance results in a lower population size of finches.B Lower seed abundance results in a greater population size of finches.C Higher seed abundance results in a greater population size of finches.D Changes in seed abundance do not affect the population size of finches.
Solution
Without the actual graphs, it's difficult to provide a definitive answer. However, generally speaking, the relationship between a food source and a population size is usually direct. This means that if there is a higher abundance of seeds (the finches' food source), the population size of finches would likely increase because there is more food available to support a larger population. Conversely, if there is a lower abundance of seeds, the population size of finches would likely decrease because there is not enough food to support a large population. Therefore, the most likely answer would be C: Higher seed abundance results in a greater population size of finches.
Similar Questions
Finches on the Galapagos islands exhibit remarkable variation in the shape of their beaks. What best explains this variation?Multiple choice question.Differences in their feeding habitsSubtle differences in the climate of different Galapagos islandsDifferences in their predatorsDifferences in their breeding strategies
How did natural selection shape the evolution of finches on the Galápagos Islands?Multiple choice question.Several different bird species migrated from the mainland to the Galápagos Islands and occupied the habitats to which they were best suited.Birds that used their beaks to crack bigger seeds acquired larger beaks in their lifetime and passed this trait on to their offspring.Birds with different heritable differences were able to better survive and reproduce in different habitats.
Galápagos medium ground finches are found on Santa Cruz and San Cristóbal islands, which are separated by about 100 km of ocean. Occasionally, individuals from either island fly to the other island to stay. This can alter the allele frequencies of the population through which of the following mechanisms?Question 4Select one:a.natural selectionb.genetic driftc.gene flowd.mutation
Why did Darwin infer that finches on Galápagos islands had undergone evolution by natural selection?Multiple choice question.Because they had the same beaks regardless of their food source.Because they all looked nearly identical.Because they were found on an island but not on the mainland.Because of the close correspondence between their beaks and their food.
