How to use this resource
This worksheet works brilliantly as extension material for your top set or as homework to deepen understanding after teaching limiting factors. The data analysis section requires careful calculation and graph plotting – perfect for developing maths skills in a biological context. Use the compensation point question as a class discussion starter about experimental design, or set the adaptation questions as independent research tasks. The variety of question styles mirrors exam papers, so it's excellent revision material in the run-up to mocks or final exams.
