Please explain your answer Date:Name:ve your answers to Questions 12 and 13 on the information and diagrambelow and on your knowledge of science.Avelage beak sizes of the seed-eating medium ground finch on one of the Galapagos Islands are shown in thethet r below. During wet years, all types of seeds are abundant, The medium ground finch prefers to eat small seedscoe easy to crush. However, during droughts (dry vears), when small seeds are not as abundant, they eat the largerseeds on the island.BeakSizeMediumground finch10.0-9.8-9.6-本9.4-9.2-9.0-Dry-year-Dry--year--Dry-year-1977198019921984Year12. How might an extended period of drought influence the ground finch population?A. Drought decreases seed availability but has no influence on the ground finch.B. Drought increases seed availability, and all ground finches would be numerous.C. The birds with smaller beaks would be more numerous.D. The birds with larger beaks would be more numerous.Beak size (mm)

Adaptive divergence or adaptive radiation is the rapid Speciation and ecological diversification within a single species or a single lineage of species in several specialised directions. Different species of finches on Galapagos Islands have evolved from one mainland species present on West coast of South America. on these islands finches got adapted to exploit different creatures and habitats and evolved into defined species. they are weeks become modified to eat different types of foods available in different niches. The ground finches are chiefly seed crushers, the size of beak is correlated with the size of seeds they eat. During drought season only larger seed is available, this large sized seed is easily utilised by large beak finches. Show sarv ability of large big finches increases as a result during prolonged drought drought season maximum amount of large beak finches are survived. Hence, Option D is correct option.Reasons for incorrect options: Option A : Drought influence the ground finches, it increased the survivability of large beak finches. So it is incorrect. Option B : Drought dicreases seed availability. So it is incorrect. Option C : Number of smaller beak finches dicreases due to shortage of small size seed. So it is incorrect.
