photosynthesis involves the expenditure of sunlight and chemosynthesis involves chemicals...
Facilitated transport occurs when a substance moves from an area of higher concentration to an area of lower without the aid of energy. Active transport involves additional energy as it is moving from a lower concentration into a higher concentration.
I think that is chemical. :)
Yes.
