What examiners said
Most candidates used the information to identify that rhinos are herbivores. Some thought it was a secondary consumer rather than primary, presumably because it is on the second trophic level. It was clear some candidates had not read the information provided as they guessed carnivore.
— Examiner report, May/June 2025, 0973/32 Q4(a) (Cambridge)
Few candidates gave the correct response. Common incorrect responses included phytoplankton, producer and secondary consumer.
— Examiner report, May/June 2025, 0973/42 Q4(b)(i) (Cambridge)
Many candidates were able to interpret the food chain. Occasionally the quaternary consumer was misidentified as a frog. The organism that occupies the first trophic level was occasionally misidentified as a primary consumer.
