In this video, I explain ALL of the content required for the "Nutrient Cycles" section for AQA A Level Biology (A2). This includes: mycorrhizae, nitrogen cycle, phosphorus cycle, fertilisers, leaching and eutrophication. Time stamps are in the comments section and the content crosses over with other exam boards too.

I also go through a few exam questions and explain the mark schemes.

Please comment if you have any questions, I'll be more than happy to answer them!! :)
