Poor BBC owe natural network (6)

I believe the answer is:

cobweb

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

'natural network' is the definition.
'cobweb' can be an answer for 'network' (I've seen this before). I'm unsure of the 'natural' bit.

'poor bbc owe' is the wordplay.
'poor' is an anagram indicator.
'bbc'+'owe'='bbcowe'
'bbcowe' with letters rearranged gives 'COBWEB'.

Can you help me to learn more?

(Other definitions for cobweb that I've seen before include "Spider silk" , "Flimsy trap for" , "Dust-covered network" , "Spider's net" , "An arachnid's mesh" .)

I've seen this clue in The Sun.
