Small world patterns in food webs
WebOct 14, 2024 · Food web structure can be understood in terms of energy transfer and biomass flow between different components of the ecosystem, either flowing from … WebA food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another. In a food chain, each organism occupies a different trophic level, defined by how many energy transfers separate it from the basic input of the chain.

WebAbstract. All organisms are ultimately dependent on a large diversity of consumptive and non-consumptive interactions established with other organisms, forming an intricate web of interdependencies. In 1992, when 1700 concerned scientists issued the first “World Scientists' Warning to Humanity”, our understanding of such interaction networks was still … WebThe analysis of some species-rich, well-defined food webs shows that they display the so called Small World behavior shared by a number of disparate complex systems.
