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 ?
Answer : (i) Parasitic (ii) Holozoic (iii) Saprophytic

(b) What is the organism like D called ?
Answer : Host

(c) Name the process E.
Answer : Egestion

(d) Give one example each of organisms like (i) A (ii) B, and (ii) C.
Answer : (i) Tapeworm (ii) Man (iii) Mushroom

(e) What is the general name of three modes of nutrition exhibited by organisms A, B and C ?
Answer : Heterotrophic nutrition

Questions . An organism A which cannot move from one place to another, makes a simple food B from the substances C and D available in the environment. This food is made in the presence of a green coloured substance E present in organs F in the presence of light energy in a process called G. Some of the simple food B also gets converted into a complex food H for storage purposes. The food H gives a blue-black colour with dilute iodine solution.

(a) What is (i) organism A (ii) food B, and (iii) food H ?
Answer : (i) Green plant (ii) Glucose (iii) Starch

(b) What are C and D ?
Answer : Carbon dioxide and Water

(c) Name (i) green coloured substance E, and (ii) organ F.
Answer : (i) Chlorophyll (ii) Green leaf

(d) What is the process G ?
Answer : Photosynthesis
