    It was percentage they were due to chance not percentage they were significantly different so it should be a low value i think
    You can say either. There is a less than 99.75% probability that the observed results were caused by chance OR There is a more than 99.75% probability that the observed results were not caused by chance OR There is a less than 0.25% chance that the observed results were caused by chance etc

    11.36 or something like that.

    For energy subsidies i had no clue and said meat takes much more energy to produce the same amount of biomass orr something and for the second one I put about meat being at a higher trophic level whereas plant foods get their energy directly from the sun

    I got so stumped on what i think was a really basic question, what data did they need to know to draw an accurate line of best fit?

    I wasn't sure but I said they need to know the range of data

    I got 9 and 7.something too

    0.025 is 99.75% i think.
    number of species was 21.. so basically work it out backwards and you get 21

    Yeah meat = hetrotrophic so less efficiemt

    plants = autotrophic so more efficient

    I got 21 in the table and 7.34 for chi squared and put 2.5% for the next one. im pretty sure the table one is 21 because it was (O-E)^2/E so O = /2.4x15 +15


    I got that too. We checked with my teacher and he says it's definitely correct

    How can two numbers work??? I cannot see how 9 could be the answer, could you explain how you got 9?

    Ahhh that was so much better than envs3 :') I did the abiotics question, there were some points I forgot but I think I went into enough scientific detail so glad i revised the soil erosion experiment last night! Hope I've scraped a B

    I didn't understand the mean question and the first stats calculation though, like most people by the sounds of it haha

    By the way for the essay i ticked one question, then changed my mind and crossed it out - will this be ok? xD

    Did any one else do the last essay, about genetic manipulation advantages and disadvantages? What did you put?
    I talked about selective breeding, inter breeding, intra breeding, cloning and genetic engineering. Anything I missed?
