  Ans1- Dark matter plays a crucial role in Galaxy formation by providing the gravitational scaffolding around which normal matter,like gas and dust, can clump and form stars and galaxies.
  
  Ans2- Photosynthesis converts sunlight into chemical energy by capturing light energy and using it to power the conversion of carbon dioxide and water into glucose.

  Dark matter’s gravity pulls things together, helping galaxies form and stay together. Without it, galaxies would fall apart.
  
  

  Photosynthesis uses sunlight, water, and carbon dioxide to make glucose (sugar) and oxygen.  Plants trap sunlight with chlorophyll and change light energy into chemical energy stored in glucose.

  In short: light energy → chemical energy (sugar).
