29、ocal environment as a result of their activity as “ecosystem engineers” and predators. The study, published in the Journal of Animal Ecology, found that ants have two distinct effects on their local environment. Firstly, through moving of soil by nest building2 activity and by collecting food they a

30、ffect the level of nutrients in the soil. This can indirectly impact the local populations of many animal groups, from decomposers to species much higher up the food chain. Secondly, they prey on a wide range of other animals, including larger prey which can be attacked by vast numbers of ant worker

31、s. Dirk Sanders, an author of the study from the universitys Centre for Ecology and Conservation, said: “Ants are very effective predators which thrive in huge numbers. Theyre also very territorial3 and very aggressive, defending their resources and territory against other predators. All of this mea

32、ns they have a strong influence on their surrounding area. ”“In this research, we studied for the first time how big this impact is and the subtleties of it. What we found is that despite being predators, their presence can also lead to an increase in density and diversity of other animal groups4. T

33、hey genuinely play a key role in the local environment, having a big influence on the grassland food web, ” Sanders said. The study, carried out in Germany, studied the impact of the presence of different combinations and densities of black garden ants and common red ants, both species which can be

34、found across Europe, including in the UK. It found that a low density of ants in an area increased the diversity and density of other animals in the local area, particularly the density of herbivores and decomposers. At higher densities ants had no or the opposite effect, showing that predation is c

35、ounteracting the positive influence. Dr Frank van Veen, another author on the study, said: “What we find is that the impact of ants on soil nutrient levels has a positive effect on animal groups at low levels, but as the number of ants increases, their predatory impacts have the bigger effect thereb

36、y counteracting the positive influence via ecosystem engineering. ”Ants are important components of ecosystems not only because they constitute a great part of the animal biomass5but also because they act as ecosystem engineers. Ant biodiversity6is incredibly high and these organisms are highly resp

37、onsive to human impact, which obviously reduces its richness. However, it is not clear how such disturbance damages the maintenance of ant services to the ecosystem7. Ants are important in below ground processes8 through the alteration of the physical and chemical environment and through their effec

38、ts on plants, microorganisms, and other soil organisms. 31. Why are ants compared to ecosystem engineers?A Because they build their own nests. B Because they collect food. C Because their activity affects the environment. D Because they are predators. 32. As predators, ants A prey on small as well a

39、s large animals. B collect nutritious food from the soil C collect food as decomposers. D prey on species much higher up the food chain. 33. Dir Sanders study centered on how ants A can manage to thrive in huge numbers. B defend their resources and territory against other predators. C attack those i

40、nvading animals for survival. D produce such a big impact on the environment. 34. What does paragraph 6 tell us?A Ants bring about a negative influence to an area when their population is small. B Ants bring about a positive influence to an area when their population is small. C Ants predation count

What still remains unclear about ants, according to the last paragraph?A What roles do ants play in the ecosystem in which they live?B How do ants affect the animal diversit

They find that the phones are more than a means of communicationhaving a mobile phone shows that they are cool and connected.The explosions around the world in mobile phone use make some health professional worried. Some doctors

44、 are concerned that in the future many people may suffer health problems from the use of mobile phones. In England, there has been a serous debate about this issue. Mobile phone companies are worried about the negative publicity of such ideas. They say that there is no proof that mobile phones are b

Signs of change in the issues of the brain and head can be detected with modern scanning (扫描) equipment. In one case, a traveling salesman had to retire at a young age because of serious memory loss. He couldnt remember even simple tasks. He wo
