Fødekæden

En fødekæde er et lineært netværk af forbindelser som starter fra producent-organismer (så som græs eller træer, der benytter stråling fra solen til at lave deres mad) og slutter hos de øverste dyr i fødekæden (så som gråbjørne eller spækhuggere).

En fødekæde viser også, hvordan organismerne relaterer til hinanden med den mad de spiser.
