Rhino using ground for feeding (10)
I believe the answer is:
nourishing
'feeding' is the definition.
(nourishing is a kind of feeding)
'rhino using ground' is the wordplay.
'ground' is an anagram indicator (grind the letters ).
'rhino'+'using'='rhinousing'
'rhinousing' with letters rearranged gives 'NOURISHING'.
'for' acts as a link.
(Other definitions for nourishing that I've seen before include "Nutritious" , "nutritive" .)
