What examiners said
Comprehensive responses • Many candidates could identify an herbivore, a secondary consumer and an organism which operated at trophic levels three and four. Limited responses • Some candidates would benefit from more practice in selecting organism types from a food web and determining their trophic levels.
— Examiner report, February/March 2026, 0610/32 Q7(a) (Cambridge)
Comprehensive responses • The majority of candidates drew an acceptable food chain. Limited responses • Some candidates need to follow instructions as some food chains given were not derived from the food web shown in the question.
— Examiner report, February/March 2026, 0610/32 Q7(c) (Cambridge)
Comprehensive response • A significant number of candidates drew an accurate pyramid of biomass on the grid. Limited responses • Many candidates would benefit from further study on the difference between a pyramid of numbers, a pyramid of biomass and a bar chart as inappropriate diagrams appeared on many scripts. • Some candidates attempted to draw a line graph using the limited data available.
