    Which of the following statement (s) about taxonomic aids is/are true I. Keys are used to identify plants and animals based on similarities and disimilarities. II.

    Read the fp,,pwomg passage and answer the questions given after it. At least 200 species of .meat-fauna. are declining in number, finds research. Humans meat-eating habits may be pushing at least 150 species of the planet.s largest animals towards the threat of extinction, a study has found. The research was published in the journal Conservation Letters. Of nearly 300 species studied, 70 per cent are in decline, and 59 per cent of the species are threatened with disappearing from the globe, said Willian Ripple, a professor at the Oregon State University in the US. "Direct harvest for human consumption of meat or body parts is the biggest danger to nearly all of the large species with threat data available,"Ripple said. "Thus, minimising the direct killing of these vertevrate animals is an imporatant conservation tactic that contribitions they make to their ecosystems," said Ripple. Researchers were part of an international collaborartion that built a list of mega fauna based on body size and taxonomy qualifying for the list were species unusually large in comparison to other species in the same class. The mass thresholds the researchers decided on were 100 kg for mammals, ray-finned fish and carilaginous fish and 40 kg for amphibians, birds and reptiles since species within these classes are generally smaller. Over the past 500 years, as humans. ability to kill wildlife at a safe distance has become highly refined, two per cent of mega fauna species have gone extinct. For all sizes of vertebrates, the figure is 0.8 per cent. "Our results suggest we.re in the process of eating mega fauna to extinction, "Ripple said . "Through the consumption of various body parts, users of Asian traditonal medicine also exert heavy tolls on the largest species," he said. In the future, 70 per cent will experience further population decline and 60 per cent of the species could become extinct or very rae," he added. Nine mega fauna species have either gone extinct overall, or gone ectinct in all wild habitats, in the past 250 years, including two species of giant tortoise, one of which disapperre in 2012 and two species of deer. "In addition to intentional harvestin, a lot of land animals get accidentally caught in snares and traps, and the same in true of gillnets, trawls and longlines in aquatic sustems," Ripple said. "And there.s also habitat degradation to contend with. When taken together, these threats con have major negative cumulative effects on vertevreate species," he said. The thene of the passage is
