CAIE A Level Biology 9700 · Classification, biodiversity and conservation
A student is studying a small woodland area. They observe three bird species feeding in different parts of the trees: one species feeds on insects in the bark, another feeds on fruits in the canopy, and a third feeds on seeds on the ground.
Outline what is meant by the terms ecosystem and niche, using examples from this woodland.
4 marks, so the mark scheme is looking for about 4 separate creditworthy points. Making the same point twice in different words earns it once.
Outline means: Give the main points briefly. Less detail than describe, but every key step has to be there. One short line per step, in order. The marks are for coverage, not depth.
