Living environment meets cosy plan (9)

Ross

I believe the answer is:

ecosystem

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

'living environment' is the definition.
'ecosystem' can be an answer for 'environment' (thesaurus). I am unsure of the 'living' bit.

'meets cosy plan' is the wordplay.
'plan' is an anagram indicator (plan can mean organise).
'meets'+'cosy'='meetscosy'
'meetscosy' with letters rearranged gives 'ECOSYSTEM'.

Can you help me to learn more?

(Other definitions for ecosystem that I've seen before include "integrated community" , "Biological community with its environment" , "The interaction of a group of organisms with their physical environment" , "Community of organisms and their environment" , "orderly collection of organisms" .)
