Abstract
Slatkovodni ekosustavi su karakterizirani brojnim interakcijama između organizama koji omogućavaju kruženje tvari i protok energije kroz ekosustav. Organizmi su razvili brojne prilagodbe koje im omogućavaju pronalazak i uzimanje hrane te opstanak na različitim tipovima staništa. Svojim međusobnim interakcijama čine hranidbeni lanac koji se razvija u hranidbenu mrežu, a proučavanjem hranidbenih mreža možemo dobiti uvid u njihove složene međuodnose i utjecaj organizama na slatkovodne ekosustave.Freshwater ecosystems are characterized by numerous interactions between organisms which enable the organic matter cycle and energy flow throughout the ecosystem. Organisms have developed numerous adaptations that allow them to find and take food, and also survive in different habitats. Their interactions form food chains which create food webs. By studying food webs we can gain insight in the complex interrelationships and the influence of organisms on the freshwater ecosystems
