Energy from sunlight is being used in an indirect way for walking the dog. Plants photosynthesize in which they absorb energy from sun and convert it into chemical energy, which is stored in organic product formed as a result of photosynthesis. When this organic compound is consumed by us, we use the chemical energy stored in that food to mechanical energy for walking the dog. Hence, the energy to walk the dog comes from sunlight.
The answer is spin.
Each quantum number that describes the two electrons in a helium atom is identical, except for the one that indicates their spin.

The evaporation process uses the sun radiation or sun’s thermal energy for vaporization of a water from the land or soil to be water vapor then in the air. Transpiration on the other hand is the same with evaporation that involves water molecules to be vaporized into the air but it is located in the stoma of the plants. It is like evaporation within plants. This is actually to have homeostasis in plants and still part of the water cycle. </span>
