    There is question 1 (b) of june 2011 biology unit 2 edexcel. here is the question:

    Zoos help to conserve rare endemic species through captive breeding programmes
    and reintroduction programmes.
    Describe how zoos use these programmes to help conserve rare species. (5 marks)

    Can u explain how to write the answer for this?

    This is what the mark scheme says:

    2. to {maintain / increase} genetic diversity/
    reduce genetic drift / eq ;
    3. protect from {predators / poachers / eq} /
    eq ;

    For captive breeding
    4. inter-zoo animal movement / eq ;
    5. selection of mates / use of stud books /
    records kept of breeding programme / eq ;
    6. process involved described e.g. IVF / AI /
    use of surrogates / DNA profiling / eq ;

    For reintroduction
    7. preparation for reintroduction described
    e.g. idea of reinforcing wild behaviour /
    idea of hacking out / reduce food intake to
    encourage hunting ;
    8. select {habitat / reserves} ;
    9. raise {awareness / education} of local
