We eat brown fruit, mostly in front of animals (5-5)

'animals' is the definition.
The answer is an example.

'we eat brown fruit mostly in front' is the wordplay.
'we' becomes 'us'.
'eat' is an insertion indicator.
'brown' becomes 'tan' (tan is a kind of brown).
'fruit mostly' becomes 'orang' (I can't justify this - if you can you should give a lot more credence to this answer).
'in front' is a charade indicator (letters next to each other).
'us' placed around 'tan' is 'utans'.
'utans' after 'orang' is 'ORANG-UTANS'.

'of' is the link.
