A food web (or food cycle) is the natural interconnection of food chains and generally a graphical representation (usually an image) of what-eats-what in an ecological community. Another name for food web is a consumer-resource system.
Food web is an important ecological concept. Basically, food web represents feeding relationships within a community (Smith and Smith 2009). It also implies the transfer of food energy from its source in plants through herbivores to carnivores (Krebs 2009). In a detrital food chain, dead organic matter of plants and animals is broken down by decomposers, e.g., bacteria and fungi, and moves to detritivores and then carnivores. Food web offers an important tool for investigating the ecological interactions that define energy flows and predator-prey relationship (Cain et al. Links in food webs map the feeding connections (who eats whom) in an ecological community. Food cycle is the antiquated term that is synonymous with food web. Ecologists can broadly lump all life forms into one of two trophic layers, the autotrophs and the heterotrophs. 1 Sink web-one or more node(s), all of their prey, all the food that these prey eat, and so on. 2  Community (or connectedness) web-a group of nodes and all the connections of who eats whom. 3  Energy flow web-quantified fluxes of energy between nodes along links between a resource and a consumer.

All species in the food webs can be distinguished into basal species (autotrophs, such as plants), intermediate species (herbivores and intermediate level carnivores, such as grasshopper and scorpion) or top predators (high level carnivores such as fox) (Figure 1). In a detrital food chain, dead organic matter of plants and animals is broken down by decomposers, e.g., bacteria and fungi, and moves to detritivores and then carnivores. Food web offers an important tool for investigating the ecological interactions that define energy flows and predator-prey relationship (Cain et al. Animals that eat ONLY PLANTS are called herbivores (or primary consumers). Animals that eat OTHER ANIMALS are called carnivores. carnivores that eat herbivores are called secondary consumers carnivores that eat other carnivores are called tertiary consumerse.g., killer whales in an ocean food web ... Food Chains & Food Webs. 1  Plants are called producers because they are able to use light energy from the Sun to produce food (sugar) from carbon dioxide and water. 2  The process by which plants make food is called photosynthesis. 3  Animals cannot make their own food so they must eat plants and/or other animals Connectedness webs (or topological food webs) emphasize feeding relationships among species, portrayed as links in a food web (Paine 1980). Energy flow webs quantify energy flow from one species to another. Thickness of an arrow reflects the strength of the relationship.

Food web offers an important tool for investigating the ecological interactions that define energy flows and predator-prey relationship (Cain et al. Food web is an important conceptual tool for illustrating the feeding relationships among species within a community, revealing species interactions and community structure, and understanding the dynamics of energy transfer in an ecosystem.
