I cant help with number 3 unless I know what the story is. On number four you just have to think about the lesson that Sasha learned or in simpler words what the conflict was, how she solved it, and how she reflected upon it, then think about your own experiences, have you gone through anything similiar and did you learn her same lesson from the experience? Hope this helps :) :)
Well if you think about it photosynthesis shows how the plants evolves so if you were to use a diagram that would support the fact that leaves take in nutrients and energy.
