grabežljivci su prirodni ubojice-životinje koje preživljavaju hraneći se drugim životinjama.govoreći o njima,najčešće mislimo na životinje koje se ne boje ostalih životinja,primjerice lavove i morske pse.te su vrste na samome vrhu hranidbenog lanca.no,gotovo sve su životinje grabežljivci, bez obzira na to hrane li se sićušnim račićima ili bivolima.biljojede (životinje koje se hrane isključivo biljkama)nazivamo primarnim potrošačima,a one na dnu hranidbenog lanca primjerice bakterije,biljke ili alge koje stvaraju vlastitu hranu nazivamo proizvođačima.što je neka vrsta više u hranidbenom lancu,to je manje ima i zato u šumama vidimo brojne jelene,ali vrlo teško je vidjeti vuka. životinje na vrhu hranidbenog lanca(grabežljivci) jedu ostale životinje,ali njih drugi ne jedu.u sredini lanca su životinje koje jedu druge ali i bivaju pojedene.
