A food chain is a linear network of links in a food web starting from producer organisms (such as grass or trees which use radiation from the Sun to make their food) and ending at apex predator species (like grizzly bears or killer whales), detritivores (like earthworms or woodlice), or decomposer species (such as fungi or bacteria).
 A food chain also shows how the organisms are related with each other by the food they eat.
 Each level of a food chain represents a different trophic level.
 A food chain differs from a food web, because the complex network of different animals' feeding relations are aggregated and the chain only follows a direct, linear pathway of one animal at a time.
 Natural interconnections between food chains make it a food web.
 A common metric used to quantify food web trophic structure is food chain length.
 In its simplest form, the length of a chain is the number of links between a trophic consumer and the base of the web and the mean chain length of an entire web is the arithmetic average of the lengths of all chains in a food web.

Triumph of the Will (German: Triumph des Willens ) is a 1935 German propaganda film directed, produced, edited, and co-written by Leni Riefenstahl.
 It chronicles the 1934 Nazi Party Congress in Nuremberg, which was attended by more than 700,000 Nazi supporters.
 The film contains excerpts from speeches given by Nazi leaders at the Congress, including Adolf Hitler, Rudolf Hess and Julius Streicher, interspersed with footage of massed Sturmabteilung (SA) and Schutzstaffel (SS) troops and public reaction.
 Hitler commissioned the film and served as an unofficial executive producer; his name appears in the opening titles.
 The film's overriding theme is the return of Germany as a great power, with Hitler as the leader who will bring glory to the nation.
 Because the film was made after the 1934 Night of the Long Knives (on 30 June) many prominent Sturmabteilung (SA) members are absent—they were murdered in that Party purge, organised and orchestrated by Hitler to replace the SA with the Schutzstaffel (SS) as his main paramilitary force.

A food fight is a form of chaotic collective behavior, in which food is thrown at others in the manner of projectiles.
 These projectiles are not made to harm or damage others, but to simply ignite a fight filled with spontaneous food throwing.
 Food fights may be impromptu examples of rebellion or violence; however, they can also be planned events.
 For example, La Tomatina is a regularly held, organized Spanish food fight in which participants pelt each other with tomatoes.
 In organized food fights, the food "weapons" are usually all of one kind, or of a limited variety.
 An impromptu food fight will use whatever food is on hand.
Cottage Rake (1939–1961) was a successful National Hunt racehorse.
 His breeder was Richard Vaughan from Hunting Hall, Castletown Roche, Co.
 Cork, Ireland.
 Before he embarked on his jumping career, he was failed by a vet on three different examinations.
 On the last of these occasions, the vet was working for Frank Vickerman, who had just become one of the first patrons of a new Irish trainer named Vincent O'Brien.
 But the deal still went through, and Cottage Rake ultimately set his trainer on the route to the top of the training ladder by becoming only the second horse to win the Cheltenham Gold Cup three years in a row.
 He achieved this hat trick from 1948–1950, beating Finnure by ten lengths in the last of these races.
 His hardest-won triumph had come the previous year when he only got the better of Cool Customer in the final 100 yards.
 Such was his partnership with jockey Aubrey Brabazon that a verse was composed about their success.
 Cottage Rake lost his form after his third Cheltenham Gold Cup triumph.
 He moved over to Gerald Balding's stable in England, but the change of scenery did not resurrect his success.
