Label the axes and provide a figure legend.Interpret the following graphs: In the graphs, the number of days are 18.. 1 day is equal to 60 sec. For the first graph, days are taken on x-axis. The mean foraging times are taken on y-axis. For the 2nd graph, percentage of prey caught during first half of winter(1-6days) were taken on x-axis and percentage of prey caught during 2nd half of winter(7-12days) were taken on y-axis.
- During the drought of 1977 on the island of Daphne Major, which of the following answers correctly explains why birds with larger beaks had a competitive advantage over other individuals? These birds were able to hold more water. These birds were able to fight off birds with smaller beaks more successfully. These birds were able to smell and locate nesting sites with more accuracy. Birds with larger beaks were better able to utilize the large seeds.Table 1: The density of dippers (Cinclus cinclus) per km of upper stream length in 18 rivers across Great Britain: the pH of stream water also shown as too their individual territory lengths (km). Data collected with the assistance of the British Trust for Ornithology in May 2001. 1.Using the information that you have been provided with, explain the relationship between acid rain and dipper abundance.Mclver beetles come in three colors: black, white, and brown. They are consumed by the Foust finch. To avoid predators, the beetles hide on the bark of trees in their environments. If the number of trees with black bark was significantly greater than the number of trees with white or brown bark, what would be the effect on the predation of Mclver beetles by the Foust finches? Far fewer black beetles would I + Which of the five conditions of Hardy-Weinberg equilibrium would be violated in this situation? V [ Select ] Genes are now mutating. Mating is no longer random. The population size is now much larger. The population would experience natural selection pressures. There is now immigration of individuals into the population.

Which of the following statements is correct? A. Population size of predators increases when their prey's population is low. B. Competition for resources is density-independent when food is plentiful. C. Discase is density-dependent because spreading occurs more easily when a population is closer together. D.

The carrying capacity of seals would decrease, as would the seal population. b. The carrying capacity of seals would decrease, but the seal population would remain the same. c. The number of seal deaths would increase, but the number of births would also increase, so the population size would remain the same. d. The carrying capacity of seals would remain the same, but the population of seals would decrease.
