    What mutualistic relationships did everyone put for the 3 examples? I put chemo synthetic bacteria in hydrothermal vents, oxpeckers and leguminous plants and bacteria on root nodules, is this right?

    I think it might stay the same, as this test was quite easy, so boundaries are likely to be high

    Answer was 10% as it was 30% in 1990 and 20% in 2010, and it was a 1 mark question
