Autotrophic and Heterotrophic organisms MCQs
Hello students! Today’s topic is autotroph and heterotroph organisms. The autotroph members are also known as producer in which an organism can do self-feed. The word autotroph is derived from the Greek word in which auto means self and troph means nourishing. On the other hand, heterotroph is also derived from the Greek word where Hetero means different and troph means nutrition. The autotrophs get their energy by the photosynthesis process and the heterotrophs gets energy by eating other plants or simply they are dependent on the other animals and plants.
