Answer 1

an apple is a fruit

Answer 2

An apple is a nutritious fruit.

Here some descriptions of the apple can be added.

As we count Apple primarily as a fruit, and it is full of varieties on nutrients, the used words are justified.

The fruit has been used as the object in the sentence, and the word nutritious is used as an adjective for qualifying the quality of an apple as the fruit.
