How much was the last question worth? I got up to the stroke question then ran out of time. How many marks am I likely to have lost?

And for the producers to the herbivores, I was confused so I said it's calculated by taking away energy loss by theoretical yield dividing that by theoretical yield and x 100 because energy is lost by heat, egestion, movement etc. I don't even know... Think I flopped this paper badly tbh :frown:

As far as I can remember, after the stroke question page, there was a one marker, a three marker, a 2/3 marker and a one marker. Hope you did well overall :smile:

Exactly half of the f215 content didn't came up. They are getting worse every year

Exactly! Hopefully I don't have to resit, seeing as it's only getting worse...

Could you use the letters more than once?

Yes it said u can use letters more than once. And I don't think B was an answer bcuz B was immobilising enzymes? And it didn't relate to any of the statements? And D was what I forgot what D was

Thank you!! That makes me feel a lot more reassured, I was dreading that they might have been a sneaky big marker at the back!

Oh **** I totally misunderstood the question!

I panicked on that question, wrote about pyramids of energy and calorimeters, biomass and pyramids of energy flow

I panicked on that question, wrote about pyramids of energy and calorimeters, biomass and pyramids of energy flow with measuring the rate of the energy flow. No clue what i did to be honest

What did you get on the picking letters question... I got.

Wtf you could reuse letters?

Estimating the energy transfer thing - what did people do?

My thought was use a bomb calorimeter to measure energy of producer and herbivore then work out % transfer using energyherbivore/energy producer x 100

B would have been the sugar syrup from starch as the enzymes would break down that starch

I found the paper hard to be fair. Couldn't remember stuff from AS (how the f*** do they expect us to do that when we have like 10 other exams in the space of two weeks) so some questions were a complete guess and I wrote so much cr*p lol. F214 was a lot easier for me hope grade boundaries are low for both units though...
