WEBA 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), or decomposer (such as fungi or bacteria ). It is not the same as a food web.
