Does the growth of a leaf violate the law of entropy, and why or why not?
A) No, because the leaf actually increases its own entropy in this process, despite the appearance that it is becoming better organized. B) No, because the increase in the entropy of the radiation passing through the leaf is greater than the decrease in the entropy of the leaf itself. C) No, because the energy increase of the leaf is exactly balanced by the energy decrease of the radiation flowing through the leaf. D) Yes, because this law is violated in situations involving energy from the sun. E) Yes, because this law is violated by living organisms.
