* Drag the correct answer into all target fields
Krill    are    small,    shrimp-like    animals    that    only    grow    to    around    5    cm    in    length,    yet    are    one    of    the    most    important    species    on    the    planet.    They    may    appear    to    be    a    relatively    sea    creature.    However,    their    position    at    the    bottom    of    the    food    chain    of    hundreds    of    larger    has    led    to    them    being    described    as    the    'fuel'    that    runs    the    engine    of    marine    ecosystems  .    There    are    85    known    species    of    krill,    amongst    the    most    important    of    which    are    Antarctic    krill    and  ,    they    congregate    in    such    large    numbers    at    certain    times    of    year    that    they    are    clearly    from    space.    Krill    form    a  critical  part    of    the    diets    of    many    birds,    fish    and    whales,    but    are    themselves    mainly    herbivorous.    They    feed    on    microscopic    plants    called    algae    that    float    near    the    surface    of    the    ocean.
