Nothing survives on fruit, it seems (6)

I believe the answer is:

olives

I'm a little stuck... Click here to teach me more about this clue!

'fruit it seems' is the definition.
I can't judge whether this defines the answer.

'nothing survives on' is the wordplay.
'nothing' becomes 'O' (looks like zero - 0).
'survives' becomes 'lives' ('live' can be a synonym of 'survive').
'on' is a charade indicator (letters next to each other).
'o'+'lives'='OLIVES'

Can you help me to learn more?

(Other definitions for olives that I've seen before include "Yellowish green fruits" , "Small tree-fruits - so live" , "Fruits from the tree of peace" , "'Oddly, I loves these fruits (6)'" , "Trees grown for their oil-producing fruit" .)
