Nutrients are recycled within natural ecosystems, exemplified by the nitrogen cycle and the phosphorus cycle. Microorganisms play a vital role in recycling chemical elements such as phosphorus and nitrogen. • For the A Level BIology exam you will be required to know this, in sufficient detail, to illustrate the processes of saprobiotic nutrition, ammonification, nitrification, nitrogen fixation and denitrification: • a) the role of saprobionts in decomposition • b) the role of mycorrhizae in facilitating the uptake of water and inorganic ions by plants • c) and the role of bacteria in the nitrogen cycle • *EXAM TIP: AQA students are not required to know the individual names of the bacteria. • This is for A-Level Biology AQA OCR Students. • #TheNitrogenCycle #Ecosystems #Nitrification #Ammonification #Nitrogen Fixation #Denitrifying #Decomposition #Thunder #Lightning #alevelbiology #alevelbiologyAQA #alevelbiologyOCR #alevelbiologypastpaper #alevelbiologyrevision #alevelbiologynotes #ASBiology #OCR • ________________________________________________ • This video is from The Ultimate Guide To A Level Biology - a super condensed, exam focused revision course that covers all of the new AQA, OCR, and Edexcel specifications. • Improve a grade GUARANTEED in A-Level Biology, Chemistry, or Maths by using our revision materials. • View the full Biology course by Rich Thompson at https://tailoredtutors.co.uk/biology • ________________________________________________ • Facebook: https://fb.me/tailoredtutors • Reviews: / reviews • Instagram: https://instagr.am/tailoredtutors • Email us if you have any questions or suggestions! • [email protected]
