* Subject: If "food" is the topic of a discussion or sentence, then it's the subject. For example:
* "Food is essential for survival." (Food is the topic of the sentence.)
* Object: If "food" is acted upon by a verb, then it's the object. For example:
* "I love to eat food." (The verb "eat" is acting upon the object "food".)
So, it's not a simple yes or no answer. It depends on the context.
