Powerpoint presentation and lots of exam questions ( including two 6 markers), on the triple content on the B4 unit.
This includes looking at pyramids of biomass and number and energy efficiency in food chains.

There are also two exam packs, one with all the questions and answers from the new OCR A gateway specification and one with questions from 21st century 9-1 specification
