Biology definition: Afood chain is a group of organisms that are consumed in a linear order, passing nutrients and energy along the way. Each organism in a food chain is at a particular trophic level, which is determined by how many energy transfers distance it from the chain’s primary...
Predator–prey type interaction is one of basic interspecies relations in the biology and ecology and it is also the basic block of the complicated food chain, food web and biochemical network structure [1–4]. Since the seminal work by Aiello and Freedman [5], species growth models with sta...

While the food-web theory has traditionally been built on the former mechanism, the latter mechanism has formed the basis of a successful theory explaining the spatial distribution of organisms in the context of behavioral and evolutionary ecology. Yet, few studies have compared these two mechanisms...

It was reshaped into a horizontally defined chain which runs from 'farm to fork'. In the resulting framework, food risks can be defined at the level of the production chain in addition to the individual product, which broadens the range of potential strategies for dealing with the newly ...
Given favourable climate conditions and vegetation, edible insects could be traded from low-income to non-consuming countries in an improved and sustainable food system and economic value chain. Conclusion Edible insects have been part of the traditional diet of many people in the tropics and ...
Plankton dynamics in the marginal ice zone of the central Barents Sea during spring: carbon flow and structure of the grazer food chain Plankton community structure was analysed during spring at four stations along a transect from the polar ice into open waters of the Barents Sea. The trans.....
