Organisms that aren’t food producers must be food consumers. This method of nutrition is described as heterotrophic (eating others).

Explain how Lucy could be viewed as “the missing link” Australopithecus Afarensis‚ commonly known as Lucy‚ can be seen by many scientific and historic facts as ‘the missing link’.
