Senior Examiner Annotations# Item Page Mark/Symbol Annotation1 10 1 0 Plan viewed no creditable material

2 10 2 0 Introduction. Do not penalise as irrelevant material

3 10 2 0 P. one tick for idea of light energy to chemical energy

4 10 2 0 P.second tick for correct reference to photolysis and using energy from ATPand reduced NADP to form glucose in light-independent reation

5 10 3 0 Et. two ticks awarded for correct references to loss of energy between trophiclevels and the different ways in which this occurs.

6 10 4 0 Irrelevant material about nutrient cycles so lose one relevance mark

7 10 4 0 Sr. One tick for pacinian corpuscle converting mechanical energy intoelectrical energy

8 10 5 0 Sr. second tick for correct reference to the functioning of light receptorstransferring light energy into electrical energy

9 10 6 0 A. correct material about chemical energy from ATP being converted intomovement energy and used in active transport. The error in referring to boththe stroma and the cristae as the site of ATP production is not a fundamentalerror so does not negate a mark

10 10 6 0 Mc. Noted as a topic however insufficient material to be worth a tick

11 10 6 0 D. one tick for Glucose produced as a result of digestion can then beconverted into other energy forms by respiration e.g. heat to maintain bodytemp

12 10 7 0 CONTENT: three topics gained two ticks and three topics gained one tick sothe best four topics were three with two ticks and one with one tick soawarded 14 marks.

BREADTH: covered 7 toipcs so awarded 3 marks

RELEVANCE: One area of irrelevant material (nutrient cycles) so lose onerelevance mark to award 2 marksQWC: Good us of terminology and clearly expessed
