These relationships pertaining to the nutri­tional factor form a. food series or food chain. They, in turn, are preyed upon by the arctic white fox (Alopex lagopus), snowy owl (Nyctea scandiaca) and other raptors — throughout the long winter and during the brief summer. The food chain or the web of relations between different organisms is a very complex one.

The soil food web is the community of organisms living all or part of their lives in the soil. The inter-relationship between plants and animals and between animals and ani­mals in the sphere of energy production and consumption results in a definite pattern of several stages of eating and being eaten up — this is referred to as the food chain. The aphids thus are primary consumers. Some live in freshwater; a few live in damp moss, in moisture at the base of leaves, or in humus. Only about 5 percent of the leaf material is grazed upon and the rest is acted upon by microorga­nisms. asked Oct 31, 2018 in Biology by Sagarmatha (54.4k points) ecosystem; neet; Welcome to Sarthaks eConnect: A unique platform where students can interact with teachers/experts/students to get solutions to their queries.

It passes from dead organic matter to microorganisms and then to detritus feeding organisms (detritivores) and their predators. Experts have ranked the 24 most damaging food-borne parasites according to number of cases, global distribution and health impact. Food handlers, people involved in preparing and serving food, working with poor personal hygiene could pose a potential threat of spreading intestinal parasites to the public in a community.
