They are larger than penne and ziti, and sometimes slightly curved, though nowhere near as curved as elbow macaroni. Rigatoni characteristically have ridges down their length, sometimes spiraling around the
Food web continued web of life". Interest in food webs increased after Robert Paine's experimental and descriptive study of intertidal shores suggesting that food web complexity was key to maintaining species diversity and ecological stability. Many theoretical ecologists, including Sir Robert May and Stuart Pimm, were prompted by this discovery and others to examine the mathematical properties of food webs. Food web A food web (or food cycle) is a natural interconnection of food chains and a graphical representation (usually an image) of what-eats-what in an ecological community. Another name for food web is consumer-resource system. Ecologists can broadly lump all life
