In Photosynthesis there is Transformation of
Option 3 is the right answer.
Photosynthesis is a process used by plants and other organisms to convert Solar energy or light energy, normally from the Sun, into chemical energy that can be later released to fuel the organisms’ activities.
Most living things depend on photosynthetic cells to manufacture the complex organic molecules they require as a source of energy.
Cells get nutrients from their environment, but where do those nutrients come from? Virtually all organic material on Earth has been produced by cells that convert energy from the Sun into energy-containing macromolecules. This process, called photosynthesis, is essential to the global carbon cycle and organisms that conduct photosynthesis represent the lowest level in most food chains.
