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 trophic level of an organism is the number of steps it is from the start of the chain. A food web starts at trophic level 1 with primary producers such as plants, can move to herbivores at level 2, carnivores at level ...

An interaction web, shown above right, [9] is similar to a topological web, but instead of showing the movement of energy or materials, the arrows show how one group influences another. In interaction food web models, every link has two direct effects, one of the resource on the consumer and one of the consumer on the resource. [ 10 ]
The concept of synonymy in zoology is reserved for two names at the same rank that refers to a taxon at that rank – for example, the name Papilio prorsa Linnaeus, 1758 is a junior synonym of Papilio levana Linnaeus, 1758, being names for different seasonal forms of the species now referred to as Araschnia levana (Linnaeus, 1758), the map ...
