APES 2.4 - 2.7 Questions and Answers

APES 2.4 - 2.7 Questions and Answers The graphs above show the population size and distribution of beak sizes in a finch population on the island of Daphne Major in the Galapagos in 1976 and 1978. Smaller-beaked finches are better suited for eating grasses and small seeds. Larger-beaked finches are better suited for cracking larger seeds and nuts. In 1977 a drought took place and the vegetation of the island was affected by the lack of rain. Which of the following was the number of finches in the population with a beak size of 10.2 mm in 1978? A 8 B 12 C 40 D 65 Which tree species grows best with full sunlight? A White oak B Hickory C Dogwood D Sweet gum E Beech 3 Which of the following best identifies the author's claim? A Aardvarks are shifting the location of their territories as a response to global climate change. B Aardvarks are a keystone species and their decline could have a trophic cascade effect on the ecosystem. C The loss of aardvarks described in the study was an isolated incident because most aardvark populations are increasing globally. D Providing aardvarks with more burrows will help them maintain their body temperature and increase survival rates. Living organisms must acquire energy from their environment. Examples of adaptations that help organisms acquire this energy include which of the following? The dark, heat-absorbing coloration of a reptile. The fangs and claws of a lion The light coloration of a peppered moth A I only B II only C I and II only D II and III only E I, II, and III Don't know?

A 8.8 mm B 9.5 mm C 10.2 mm D 13.8 mm B 9.5 mm Which of the following statements best explains the changes in the size and composition of the population of finches after the drought? A The total number of finches in the population increased, and the smaller-beaked finches were more successful in the drier environment. B The total number of finches in the population increased, and the larger-beaked finches were more successful in the drier environment. C The total number of finches in the population decreased, and the smaller-beaked finches were more successful in the drier environment.

Opportunistic use of estuarine habitat by juvenile Bull Trout, Salvelinus confluentus, from the Elwha River before, during, and after dam removal. Environmental Biology of Fishes 101: Which of the following best identifies the author's claim? A Bull trout experienced high mortality rates as a result of the formation of the estuary and sediments released during dam deconstruction. B Bull trout are adaptable to a variety of habitats and were able to survive in the river habitat during the dam deconstruction. C Bull trout remained in the estuary system after the dam deconstruction because the disruption had irreversibly altered the river habitat. D Bull trout are unable to live in high sediment loaded waters and migrated to avoid the conditions introduced during dam deconstruction.
