Large enough flocks of birds can also be a factor in the weather. When millions of migratory seabirds arrive in the Arctic each summer,they bring a huge burst of guano (bird waste). As bacteria go to work on the guano and break it down, they emit ammonia. As sulfuric acid and water ...
Despite the origin of reptiles in Late Carboniferous time, amphibians continued to prosper into Early Permian time. During the Permian Period (290-251 million years ago), however, reptiles diversified and apparently began to replace amphibians in various ecologic roles, probably because the reptiles h...
332篇The Ecological Roles of Birds 鸟类提供了许多宝贵的生态服务,其中最重要的服务之一是散播植物种子。种子散播使植物能够迁移到新的领土,减少与自己物种的其他物种的竞争,从而增加存活率。事实上,如果你喜欢辛辣的食物,你应该感谢鸟类,因为它们在辣椒的进化过程中发挥了关键作用。在一个进化伙伴关系的例子中,辣椒植...
In turn they are ingested by many kinds of predators. Thus, the roles of the dinoflagellates in marine planktonic food webs are very diverse. The present paper reviewed the kind of prey which mixotrophic and heterotrophic dinoflagellates are able to feed on, feeding mechanisms, growth and ...

Fungi is a kingdom of living organisms that play very important roles within ecosystems. Examples of fungi are mushrooms, mold, and yeast, and they typically grow in moist, damp environments.Answer and Explanation: The two ecological roles of fungi are decomposition of other organisms and ...
In the biological context, ecology is studied as a separate division in which the interdependence of an ecosystem's biotic and abiotic components is evaluated. The beneficiary role played by any ecosystem component which is useful to the other ecosystem components is termed ecological roles....

many open questions on the ecological and evolutionary roles of verbenone for the highly diverse group of bark beetles with various life histories. Is it an actual anti-aggregation pheromone synthesised by the beetles themselves or rather an indicator of poor host quality (degradation or competition)...
The Ecological Roles of Birds Birds provide numerous invaluable ecological services, and one of the most important is by scattering plant seeds. Seed dispersal enables plants to migrate into new territory and reduces competition with others of their own species, thereby increasing survival rates. In ...
