A freshwater aquatic food web. The blue arrows show a complete food chain (algae → daphnia → gizzard shad → largemouth bass → great blue heron). A food web is the natural interconnection of food chains and a graphical representation of what-eats-what in an ecological community.
The resulting deposits are called illuvial deposits. Cutans are a type of illuvial deposit. [2] Illuvium includes organic matter, silicate clay, and hydrous oxides of iron and aluminum. Illuvial deposits of clays, oxides, and organics accumulate in subsoil as distinctive soil horizons classified as "B horizons" or "zones of illuviation".
An example of a topological food web (image courtesy of USDA) [1]. The soil food web is the community of organisms living all or part of their lives in the soil. It describes a complex living system in the soil and how it interacts with the environment, plants, and animals.
Alluvium and adjacent constituents Alluvium deposits in the Gamtoos Valley in South Africa An alluvial plain in Red Rock Canyon State Park (California) Alluvial river deposits in the Amazon basin, near Autazes, AM, Brazil. The seasonal deposits are extremely fertile and crucial to subsistence farming in the Amazon Basin along the river banks.
The observed values of connectance in empirical food webs appear to be constrained by the variability of the physical environment, [4] by habitat type, [5] which will reflect on an organism's diet breadth driven by optimal foraging behaviour. This ultimately links the structure of these ecological networks to the behaviour of individual organisms.
An alluvial river is one in which the bed and banks are made up of mobile sediment and/or soil. Alluvial rivers are self-formed, meaning that their channels are shaped by the magnitude and frequency of the floods that they experience, and the ability of these floods to erode , deposit , and transport sediment .

A series of adjacent alluvial fans coalescing in a basin at the foot of a mountain range. Balkanization The political fragmentation of a larger region or state into multiple smaller regions or states, often implying mutual hostility or lack of cooperation between such units, as has occurred frequently in the Balkan Peninsula of southeastern Europe.
