Answer:
The grammatical feature is " It has a compound predicate"
Step-by-step explanation:
Predicate is what gives more information about the subject in a sentence.
It tells us what the subject is doing . Predicate modifies the subject.
We have simple predicate, compound predicate and complete predicate in a sentence.
"Your body needs energy to grow and heal itself" is a compound predicate joining two verbs but one subject in a sentence.
The predicate is given as
Subject: Your body
Predicate: needs energy to grow and heal itself.
