In this section, each item consists of six sentences of a passage. The first and sixth sentences are given in the beginning as S1 and S6. The middle four sentences in each item have been jumbled up and labelled as P, Q, R and S. You are required to find the proper sequence of the four sentences and mark your response accordingly on the Answer Sheet. S1: Each organism is adapted to its environment. S6 : What can be taken in and broken down depends on the body design and functioning. P : There is a range of strategies by which the food is taken in and used by the organism. Q : For example, whether the food source is stationary (such as grass) or mobile (such as deer), would allow for differences in how the food is accessed and what is nutritive apparatus used by a cow or a lion. R : The form of nutrition differs depending on the type and availability of food material as well as how it is obtained by an organism. S : Some organisms break down the food material outside the body and then absorb it and others take in the whole material and break it down inside their bodies. The correct sequence should be

Photosynthesis is the process by which autotrophs take in susbstances from the outside and convert take insubstances from the outside and convert them into stored formes of energy .the materials is taken in the form of carbon dioxide and water which is converted into carbohydrates in the presence of sunlight chlorophyll . The carbohydrates which are not used immediately are stores in the form of starch , which serves as the internal energy reserve to be used as and when required by the plant . The complex substances have to be broken down into simpler ones before they can be used for the unkeep and growth of the body . Heterotrophs depend for energy on :
