    pretty damn sure thats right....

    that's just me sounding modest, its definitely right (unless you needed to round to 0.7)
    You would have needed to say 0.7 or 0.666667 (as many 6's as you want as long as it ends in a 7).

    couldn't you say snails loose less energy via movement, so more is passed on to Thrushes?
    Energy is lost in a food chain by:
    1 respiration for movement and maintaining body temp
    2 inedible parts such as bones and hooves
    3 indigestible parts removed as faeces

    So less energy would be passed on to Thrushes by movment

    The exam was ridiculously difficult! AQA should be more lenient and lower the grade boundaries, it makes more sense.
    It was very difficult, it's hard to say what the minority/majority is on this because this paper received very mixed opinions. I hope for my future it's similar to last year

    It is invertebrates because the questions was asking for ANIMALS not plants.

    Could you put (for those question including snails and thrushes) that biomass is lost due to, when being eaten, not all parts of the body being edible (eg. bones) and then, for the following question, write about how the % biomass lost was lower because snails have no bones, hence meaning they could eat more of the snail? (I feel kinda stupid for putting that now after reading the unofficial mark scheme )

    What did people get for the question about all boys drinking and why was the hypothesis not valid??
    Can't remember about the drinking but I put that the sample size was too small because they only asked 100 boys

    I put for the snail and thrush one that the food chain may have been incomplete (ie the thrush may have predators)
    Is this wrong then?

    Also, anyone have any idea what the A* boundary might be? Do you think it will go up or down from last year?
