    As we go along a habitat, the abundance of different species varies. This is because different specifies out compete each other in different conditions. Eg soil depth and salinity

    How do detrititivores help plants make new cells?
    OMG...dats a hard one...
    do they break down dead materials...to increase surface area for saprophytes and this makes the soil fertile as it will contain the minerals needed to make a new plant cell?

    CGP isn't very helpful imo, best one for me is the lonsdale ESSENTIALS GCSE OCR Gateway Biology B revision guide.
    I've got Collins Revision books but I also have Lonsdale Essentials as well (got it for £3 pounds for the 3 science books together off eBay )

    Hi people,

    This is my mindmap for B5. I missed out some topics because they aren't strictly related to the human body. Sorry it's so squashed together, there's so much you need to know! Hope it helps.
    It's very detailed

    mm...ok..in the stomach it is acidic (HCl provides right conditions as pH needs to b low...in intestine it is alkaline so its high nd, those in the mouth require a slightly acidic/neutral pH...is there protease enzymes in the mouth? the last line about the mouth was frommy textbook...
