Question 31:
All organisms need energy (in forms like ATP, chemical energy from food) to perform life functions (growth, reproduction, metabolism). So the answer is energy (or ATP, but energy is broader here).
The sun is the ultimate energy source for life on Earth. Photosynthetic organisms use sunlight, and others get energy from organisms that rely on sunlight, so the sun (solar energy) is ultimate.
In photosynthesis, light energy is converted to chemical energy stored in organic compounds (like glucose, a sugar). So the energy is stored in organic compounds (or glucose - related molecules).
