This powerpoint presentation covers Option F.5 (Metabolism of Microbes) in the IB Biology curriculum. This subtopic is quite short and discusses heterotrophy, autotrophy, phototrophy and chemotrophy.
Each slide is labelled with the specific learning objective and animation/video links are provided in the slide notes. The slides are formatted to print well for handouts or revision and I can provide a pdf version upon request.
As always, please let me know if you have any suggestions for improvements. These are always a work in progress!
**IB Biology Learning Objectives
F.5.1 – Define the terms photoautotroph, photoheterotroph, chemoautotroph, and chemoheterotroph
F.5.3 – Compare photoautotrophs with photoheterotrophs in terms of energy sources and carbon sources.
F.5.5 – Draw and label a diagram of a filamentous cyanobacterium.
F.5.6 – Explain the use of bacteria in the bioremediation of soil and water.
