This conversion of one form of energy into another is called: transduction.
Explanation:
In the above scenario, the light energy received by Samantha on opening her eyes to see the flowers was then converted into neural messages to process by the brain. This kind of conversion of energy is known as transduction.
Transduction is done as the physical energy cannot be directly transmitted to the brain. It is then converted into electrical signals like neural impulses and transmitted to the brain. The transmission of signals from an exterior of cell to its interior is known as cell signaling or signal transduction. To achieve appropriate response, the signals received by cells should be effectively transmitted to another cell.
