The scenario in which sunlight is absorbed by plants for photosynthesis is a classic example of energy conversion into a usable form. During photosynthesis, plants capture sunlight, which is a form of solar energy, and convert it into chemical energy. This process leads to the formation of glucose, which serves as food for the plant and can be used as energy by other organisms that consume the plant. This transformation is fundamental to the energy cycle in ecosystems, illustrating how solar energy is made available for growth and sustenance of life.

In contrast, while the other scenarios involve energy transformations, they do not clearly depict the creation of a usable form of energy in the context of a biological process. For example, a motor burning fuel generates power but relies on chemical energy stored in the fuel, rather than converting an external energy source into a usable form for organic life. Similarly, a candle burning produces heat, which is indeed energy release, but it is primarily a combustion process that doesn’t transform energy to support life forms. Lastly, heating water to create steam involves converting thermal energy into mechanical energy, which can be useful, but does not convert an energy source into a form that is crucial for biological processes.
