A。解析:本题考查干旱生态系统中的生物竞争关系以及相关词汇。在干旱生态系统中,仙人掌(cactus)和骆驼(camel)都是生物(biotic factor),它们都需要水来生存,所以可能会互相竞争水源。选项B岩石(rock)和沙子(sand)都是非生物,不会有争夺水源的生物行为。选项C阳光(sunlight)和云(cloud)是非生物,不存在生物间争夺水源...
In their valuation study, Frank Heuts and Annemarie Mol asked, “What is a good tomato?” (Heuts and Mol2013). Their study shows that different groups value tomatoes in different ways. For example, for people who transport tomatoes, a good tomato should be firm, while for others, the natu...
(Figure2A, D). This requires the interaction of AS1 and RS2 with HIRA, a chromatin-remodeling factor that could alter local chromatin organization at theKNOX1loci [95]. It becomes evident that the ARP/KNOX regulatory module is mutually exclusive, common in most simple leaved species with the...
Disease is a prime example of a density-dependent factor. Diseases spread rapidly in populations with high density. The closer proximity of individuals in a dense population enhances the transmission of diseases. Parasitism also increases in more crowded populations, as parasites can spread more quickl...
Agrilus planipennis(emerald ash borer) from the Buprestidae family was identified as a primary biotic factor causing dieback in Fraxinus species (Table5). Symptomatic trees had exit holes on trunks, bark damage and bark loss, reduced foliage density, epicormic branching, scaffold cracks, branch fra...
An example of a pond ecosystem This very complex interaction of living things and their environment has been the foundation of energy flow and recycling of carbon and nitrogen. Anytime a ‘stranger’ (living thing(s) or external factor such as a rise in temperature) is introduced to an ecosy...
