Final answer:
Growing corn converts radiant energy into chemical energy through the process of photosynthesis, with chlorophyll absorbing sunlight to produce glucose.
Step-by-step explanation:
The object that converts radiant energy to chemical energy is c) Growing corn. This process of conversion occurs in plants through photosynthesis, where plants absorb sunlight and convert it into glucose, a form of chemical energy. This energy is stored and can be released when the glucose is consumed as food.
The molecule chlorophyll is responsible for absorbing the energy of a photon during this process. In contrast, a radio converts electrical energy into sound energy, a wind turbine converts kinetic energy from the wind into electrical energy, and a solar panel converts radiant energy into electrical energy.
