Answer 1

Imagine I get all my energy from eating potatoes. With that energy I build bidets. How much of the bidet is made from potato?
Me, potato, and bidet are as plant, sunlight, and fruit in your example.
Plants *transform* the energy from sunlight, store it, and use it to build something new.
So insofar as there’s any truth to the fruit being made from sunlight, well it’s important to realize that its not made of sunlight. It’s made using energy harvested with photosynthesis, like my bidets are made with energy harvested through gorging myself on potatoes
