- A rain forest habitat is located in an equatorial area with a warm, wet climate. Nearby is a savanna, where the climate is equally warm but much drier. Species diversity is much higher in the rain forest. Which rain forest habitat characteristic most likely explains this difference? O More disturbances, leading to rapid species turnover O More complex habitat structure, enabling greater food availability O More complex habitat structure, enabling greater niche specialization O Fewer disturbances, leading to rapid population growth of a few species O Fewer open spaces, leading to inability of organisms to leave the habitatThe figure below shows the relative abundance (y axis) of shrubs in an ecosystem in the years following a fire (x axis). The shrubs in this ecosystem fall into two functional groups: fıre recruiters and fıre persisters. FIRE-RECRUITER SYNDROME FIRE-PERSISTER SYNDROME 10 100 Fire LOG YEARS If fire frequency decreased significantly in this ecosystem, which group would be benefited? O Both functional groups would benefit equally O Fire recruiter species O Fire persister species RELATIVE SHRUB SEEDLING ESTABLISHMENTFour of the following are characteristics that make some species especially vulnerable to ecological and biological extinction. Select the exception. O Low reproductive rates O Small territories Feeds at high trophic level O Narrow distribution Rare
- Which of the following statements related to classifications of rarity and extinction is TRUE? A species with an extensive geographic range and large local populations cannot be vulnerable to extinction. O Once species are the list of endangered species, they can never recover. O Species that are the most vulnerable to extinction have small population sizes, broad habitat tolerances, and narrow geographic ranges. O The majority of bird species that have gone extinct were those restricted to islands.do you think that loss of species (species extinctions) are something that humans should be concerned about? Support your answer with at least 2 supporting details.R The bat species will not overlap in their distribution on the island because competition will have resulted in random extinction on each side of the island. Submit Q10. On an adventure to a faraway place, you discover two previously unknown species of woozle. You notice that purple woozles live on the ground and orange woozles live high up in the trees. You gather up all of the purple woozles (they're easier to catch) and take them to a zoo. The next year, when you return to gather up the orange woozles, you find that they now live on the ground as well as in the trees. Based on what you know about niches and competition, which of the following is TRUE? Competition between purple and orange woozles cannot be responsible for where you found them on the island. The fundamental niches of orange woozles does not include ground habitat. On the ground, purple woozles are probably better competitors than orange woozles.

- A very rapid exponential increase in a population only occurs when: O a. It is a tropical species. O b. It has a very short generation time. O c. There is an ideal temperature. O d. There is unlimited food and space. O e. It has asexual reproduction.Give your response to the following statement: “Eventually, all species become extinct. So it does not reallymatter that the world’s remaining tiger species or atropical forest plant are endangered mostly because ofhuman activities.” Be honest about your reaction, andgive arguments to support your position.One concept of conservation biology is known as minimum viablepopulation. Some species’ populations are so fragmented andsmall that they may have very little genetic variability left. Withminimal genetic variation in the population, there is little likelihoodthat a population can adapt to an environmental threat, such as anew disease. Florida panthers are at or below the minimum viablepopulation level (estimated population less than 80). 1)Do you think that it is practical to use limited resources toconserve a population like the Florida panther? 2)Why?
- EFFECT OF SUGAR SOLUTION ON THE HEIGHT OF PLANTS Average Initial Height (centimeters) Plant Percent Sugar Solution Final Height (centimeters Group 2 30 10 2 28 15 30 10 40 (died 50 idied Jose does an experiment on the effect of different sugar solutions on the growth of plants. He watered different groups of the same type of plants with solutions of varying sugar percentages. Jose hypothesized that more sugar in a solution would cause plants to grow larger in the same amount of time. Based on the data table below, what can Jose best conclude about his hypothesis? O Jose's hypothesis is supported, plants grow larger given a more concentrated sugar solution O Jose's hypothesis is not supported, plants grow best when not exposed to any sugar solution O Jose's hypothesis is supported, plants grow larger given a less concentrated sugar solution O Jose's hypothesis is not supported, all plants die when exposed to any sugar solutionChanges in a population of Monkey-eating eagles are shown in the graph below. Referring to labeled X, which statement best explains the section of this graph? X Time a. Resources are extremely high while predation is low O b. The Monkey eating eagles are no longer in competition for resources with other species O C. The monkey eating eagles population has reached its carrying capacity o d. Interbreeding is occurring between members of different species Population sizeWhich of the following is an example of biological magnification? O Increasing concentrations of chemicals are present in organisms at higher trophic levels. Explosive expansion of species following an ecological disturbance increase diversity. O Diversification of species depends on the size and continuity of their regional habitat. Members of a species increase in size over time because the largest organisms are more fit. Larger organisms utilize more abiotic resources than smaller organisms.
