Summary Introduction
To analyze:
Autotrophs are producers and heterotrophs are consumers.
Introduction:
Organisms are divided into two broad categories based upon their nutrients and energy: autotrophs and heterotrophy. Autotrophsareproduces their own food from the help of sun light or chemical energy. Heterotrophs do not produce their own food, they depend on autotrophs. In the autotrophs involve plants which are the primary producer and in heteroptrophs involve animals which are characterized as consumer.
