I haven't looked over that side yet but I'm pretty sure you'll need a general idea just in case you need to provide detail for a long answer question!! I'd say just know the percentages of energy transfer in the back of your brain like I doubt there'll be a lot on that

What are the places we need to learn about for populations and sustainability because we never did that in class? I think one might be the Galapagos but idk any others, and what do we have to know about them?

In the chapter on cloning and technology- microorganisms and biotechnology, there's a very chunky thing on how microorganisms are used for baking, brewing, cheese-making and yoghurt making. Do we have to know this in detail or just the specific microorganisms involved?

if anyone has a summary for it, please share :smile:

here's a snippet from the cgp book!! I'm only learning this much for that aspect of the topic so I think it should be okay if you know this much Screenshot 2023-06-09 085446.png

From the 2011 paper it was the photosynthesis big mindmap diagram thing - shows the reactions in a leaf cell of a flowering plant
