An organism A which cannot move from one place to another makes a simple food B from the substances C and D available in the environment. This food is made in the presence of green-colored substance E present in organs F in the presence of light energy in a process called G. Some of the simple food B also gets converted into a complex food H for storage purposes. Does this food give a blue-black color with iodine solution?

- organism A
- food B?
- food H?
