(i)

State with a reason whether pangolins are autotrophic or heterotrophic.

[1]

Markscheme

heterotrophic because it feeds on/eats food/other organisms /eats ants/termites/ doesn’t photosynthesise/does not produce its own food;

Do not accept “it is not autotrophic” as it is part of the stem question.

Examiners report

The identification that pangolins are heterotrophic as they need to feed on other organisms because they cannot produce their own food was done effectively. However, every now and again scripts were observed with the answer "autotrophs", or candidates not getting the marking point as they omitted the reason for stating that pangolins are heterotrophic.
