HomeQ&AThe organisms A, B and C can obtain their food in three different ways. Organism A derives its food from the body of another living organism which is called its D, without killing it. The organism B takes in the solid food by the process of ingestion, digests a part of this food and throws out undigested food in the process called E. The organism C obtains its food from dead and decaying plants. (a) What is the mode of nutrition of (i) organism A (ii) organism B, and (iii) organism C? (b) What is the organism like D called? (c) Name the process E. (d) Give one example each of organisms like (i) A (ii) B, and (iii) C. (e) What is the general name of three modes of nutrition exhibited by organisms A, B and C?
