Leaves absorbing light energy sunlight is a physical factor , leaves taking in carbon dioxide and releasing oxygen air/gases are physical factors , and water and minerals being taken up through roots water and minerals are physical factors all represent interactions with physical aspects of the environment. Options D and E involve other organisms, which are biotic factors.
