21. The light energy it absorbs turns into heat ( in almost all materials ). 22. Another defense is photochromic materials able to become opaque under high light energy densities. 23. The light energy captured by ATP and NADPH which temporarily store and transport energy. 24. The interaction between the light energy and the receiver material converts light to heat. 25. We are talking rays not photons ( which are packets of light energy ). 26. Their chloroplasts absorb a major portion of the light energy used by the leaf. 27. In this way, light absorption turns light energy into heat. 28. Bioluminescence is a form of chemiluminescence where light energy is released by a chemical reaction. 29. :: : Under the normal condition, most of the absorbed light energy turns into heat. 30. Cataracts cannot be removed with a laser ( an intense beam of light energy ).
