Detailed explanation-1: -All of the interconnected and overlapping food chains in an ecosystem make up a food web. Organisms in food webs are grouped into categories called trophic levels. Roughly speaking, these levels are divided into producers (first trophic level), consumers, and decomposers (last trophic level).
Detailed explanation-2: -A food chain outlines who eats whom. A food web is all of the food chains in an ecosystem. Each organism in an ecosystem occupies a specific trophic level or position in the food chain or web. Producers, who make their own food using photosynthesis or chemosynthesis, make up the bottom of the trophic pyramid.
Detailed explanation-3: -Each level or link in a food chain or a food web is called a) a trophic level. A trophic level is the position that an organism occupies within the food chain or web of that particular ecosystem. Trophic levels include producers, primary consumers, secondary consumers, tertiary consumers, and decomposers.
Detailed explanation-4: -Another name for food web is consumer-resource system. Ecologists can broadly lump all life forms into one of two categories called trophic levels: 1) the autotrophs, and 2) the heterotrophs.
Detailed explanation-5: -A food chain only follows just one path as animals find food. eg: A hawk eats a snake, which has eaten a frog, which has eaten a grasshopper, which has eaten grass. A food web shows the many different paths plants and animals are connected. eg: A hawk might also eat a mouse, a squirrel, a frog or some other animal.
