Food chain in a Swedish lake. Osprey feed on northern pike, which in turn feed on perch which eat bleak which eat crustaceans.. A food chain is a linear network of links in a food web, often starting with an autotroph (such as grass or algae), also called a producer, and typically ending at an apex predator (such as grizzly bears or killer whales), detritivore (such as earthworms and woodlice ...
This table includes mainly food fish species, but also listed are crustaceans (crabs and shrimps), cephalopods (squids and cuttlefishs), bivalves, and a reptile (softshell turtle). Note that Oreochromis niloticus and Penaeus monodon appear twice, because substantial amounts are harvested from the wild as well as being extensively raised through ...

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.
