It takes hard workers to keep it provided with meals (8)
I believe the answer is:
anteater
'it takes hard workers to keep it provided with meals' is the definition.
The definition suggests a singular noun which matches the answer.
This is all the clue.
Can you help me to learn more?
(Other definitions for anteater that I've seen before include "Insect consumer" , "It feeds on termites, etc" , "Scaly insectivore" , "Long-snouted insectivore" , "Long-tongued mammal" .)
