ESTRATÈGIES DE SUPERVIVÈNCIA. ENTRE EL PERILL I L'ENGINY
Les relacions que s'estableixen en un ecosistema entre els organismes de diferents espècies resulten sorprenents i ingenioses. Aquests contactes poden suposar des d'un benefici mutu fins a la mort d'una d'elles per alimentar-se de l'altre. Aquestes relacions, a vegades perilloses, són molt variades i sovint requereixen molta imaginació.
