Hi there Autotrophs and heterotrophs, phototrophs and chemotrophs is listed above as SL but I can only see it in HL. Is that correct? Thanks.
2.2: Energy and Biomass in EcosystemsAh yes - I have already covered productivity, but that’s helpful with the concept of primary productivity. Thank you!
2.2: Energy and Biomass in EcosystemsNo - the maths is not needed for SL - just the concept of productivity and what is primary productivity
2.2: Energy and Biomass in EcosystemsGreat thanks for the clarification! Would you recommend teaching the full HL content 2.2.23 to both HL and SL then?
2.2: Energy and Biomass in EcosystemsNo, it's at SL too but perhaps is poorly worded, being referred to as "productivity". Check 2.2.13, 2.2.20, and it is also referred to in topic 5 SL content - 5.1.13. I'd teach it. See slide 10 in my slides and I had all my students do the practicals...
2.2: Energy and Biomass in EcosystemsChecking the course guide, I think the information about Primary productivity is now HL only, unless I'm mistaken?
2.2: Energy and Biomass in EcosystemsHi Naomi - I've updated the marking points.
Data-based activity - Topic 8.3 - Air pollution (Answers)Hi All - do you have a few sample marking points for c and d by any chance?!? Thanks
Data-based activity - Topic 8.3 - Air pollution (Answers)Then no, I don't think graphing the individual questions is necessary unless it really helps you answer the RQ.

Site authorHi Ursula, Yes photoautotrophs and chemoautotrophs are HL only. "All living organisms can be classified as autotrophs or heterotrophs." is an SL statement.
