What type of organisms obtain their energy by eating producers

Heterotrophs

A major difference between autotrophs and heterotrophs is that the former are able to make their own food by photosynthesis whereas the latter cannot. Photosynthesis is a process that involves making glucose (a sugar) and oxygen from water and carbon dioxide using energy from sunlight. Autotrophs are able to manufacture energy from the sun, but heterotrophs must rely on other organisms for energy.
