Living cargo in disarray (7)
I believe the answer is:
organic
'living' is the definition.
(I've seen this before)
'cargo in disarray' is the wordplay.
'disarray' indicates an anagram.
'cargo'+'in'='cargoin'
'cargoin' is an anagram of 'ORGANIC'.
(Other definitions for organic that I've seen before include "(Compound) containing carbon" , "Fundamental" , "Formed from living things - no cigar for this one" , "Natural (farming)" , "Naturally grown" .)
