How Does A Food Web Provides Stability To The Ecosystem. A novel hypothesis is presented which relates the complexity-stability relationship to evolutionarily history of the community. Food chains have no effect on improving the adaptability and competitiveness of the organisms while more complex food webs improves the adaptability and competitiveness of the organisms.
Diversity can operate to enhance the stability of ecosystem functions at various ecological scales. Used empirically estimated community matrices of the generalized LotkaVolterra model to show that simultaneous occurrence of strong top-down effects consumer control at lower trophic levels and strong bottom-up effects donor control at higher trophic levels in the patterns of Jacobian elements in real food webs is important to. Given that a food web is complex and interlinked isolation or separation of some food chains that make up the food web does not affect the ecosystem stability.
In food web stability of the ecosystem increases by the presence of complex food webs.
It contends that the architectural flexibility arising from foraging adaptation of consumer species is key to explaining linkage patterns and persistent mechanisms of complex food webs. Energy transfer is through food consumption so a food web essentially demonstrates the relationship of who eats who in an ecosystem. The mechanisms governing the stability of food webs has been of interest to ecologists for decades MacArthur 1955 and structures linked to increased food web stability are known to arise within the com-plex feeding interactions that make up food webs Inter-Research and Her Majesty the Queen in Right of Canada 2013 wwwint. For example genetic diversity can enhance resistance to environmental perturbations.
