Part of biome in Spain with warm spring (9)
I believe the answer is:
ecosystem
'warm spring' is the definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.
'part of biome in spain' is the wordplay.
I cannot quite understand how this works, but
'part' could be 'system' (system is a kind of part) and 'system' is present in the answer.
'of' could be 'o' and 'o' is present in the answer.
'spain' could be 'e' (abbreviation for Espana) and 'e' is found in the answer.
A single letter 'c' remains which might be clued in a way I don't understand.
This explanation may well be incorrect...
'with' acts as a link.
Can you help me to learn more?
(Other definitions for ecosystem that I've seen before include "orderly collection of organisms" , "Community of organisms and their environment" , "Biological community with its environment" , "The interaction of a group of organisms with their physical environment" , "integrated community" .)
