    Same I'm pretty sure these were the numbers but that six mark was a blessing
    That was the numbers but you read the question wrong. It asked for PLANTS to SHEEP. The first box (200,000) WAS NOT PLANTS. The SECOND box was PLANTS. The THIRD was SHEEP (200/4000 x 100 = 5%)

    I thought the paper was very vague and I hadn't seen questions in that style before…

    My school compiles all questions from 2012 onwards on each module (including Chemistry and Physics) into a booklets for revision so I thought that this paper would be a breeze because I had done so much practise, but now I'm not sure where I stand.

    Also, I'm kind of annoyed at how simple the topics were. In a sense it was easy, but if I've spent three years of my life studying for it to come down to one hour and fifteen minutes, I want it to be worthwhile! Where was the nitrogen cycle and protein synthesis? I wanted the hardcore questions I studied so hard for!

    and efficiency is energy available to next level divided by energy available from previous level
    there was 400kj of energy available to next level
    and 20000 was available from previous
    therefore efficiency is 2 %

    I talked bout how the habit numbers decreased so could become extinct cause no habitat to live and get food from. Also destroying Habits means less variety of species and no food source maybe the would have to develop another ecological niche

    The sheep was also to humans so plants get 200000 and sheep get 4000 so I did 4000(useful energy) divided by the total intake the plants got

    Anyway It doesn't matter anymore can't hang answer

    What waste number after sheep to humans I think I get it

    I'm pretty sure if it asks for sheep, then you do the sheep's amount (next level. 200) over the previous which is plants. I might be wrong, but that's what i think.

    I put 5% but not sure if I calculated the correct arrow. What did everyone get for the % chance of the baby having weird thumbs or cystic fibrosis because I think I messed that one up too?

    was the 6 marker 2 percent for efficiency?
    I got 5%

    I said this and also about more intraspecific and interspecific competition for resources and habitat.

    I said the reason the two where the same is due to your maximum vital capacity and that substance X was Carbon Dioxide as it rises when you exercise. but I might be wrong.
