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.
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 ...
An example of a topological food web (image courtesy of USDA) [1]. The soil food web is the community of organisms living all or part of their lives in the soil. It describes a complex living system in the soil and how it interacts with the environment, plants, and animals.
Though technically the fair runs from Jan. 12 to 28, there is a Ride-A-Thon (rides, limited food vendors, but no shows) from 5 to 10 p.m. Thursday, Jan. 11. The Ride-A-Thon is $25 and includes ...
In order to more efficiently show the quantity of organisms at each trophic level, these food chains are then organized into trophic pyramids. [1] The arrows in the food chain show that the energy flow is unidirectional, with the head of an arrow indicating the direction of energy flow; energy is lost as heat at each step along the way.

The pelagic food web, showing the central involvement of marine microorganisms in how the ocean imports nutrients from and then exports them back to the atmosphere and ocean floor. A marine food web is a food web of marine life. At the base of the ocean food web are single-celled algae and other plant-like organisms known as phytoplankton.
Maker Faire 2008 was held on May 3–4, 2008, at the San Mateo County Event Center. Highlights of the Faire included a human-sized Mouse Trap board game, kinetic squid sculpture, 55' wingspan kinetic steel butterfly, bicycle-powered music stage, a solar-powered chariot pulled by an Arnold Schwarzenegger robot, [13] and over 500 other booths from different makers.
In 1981, Ingham earned a PhD from the Colorado State University in microbiology with an emphasis in soil. [citation needed] Along with her husband Russ, who has a doctorate in zoology emphasizing nematology, she was offered a post-doctoral fellowship at the Natural Resource Ecology Lab at Colorado State University.
