Plants contain the carbohydrates starch and cellulose. In the spring when stem growth is at its fastest rate, In
cellulose production rates are increased in some plants.
the months with less sunlight, the level of starch decreases in some plants. What does this information demonstrate?

Ibelieve it is b. proton.hope my answer has you : )

Answer is: the equilibrium  shifts toward the reactants, to the left side of chemical reaction.it is because lead(ii) nitrate dissociates in water: pb(no₃)₂ → pb²⁺(aq) + 2no₃⁻(aq).according to lechatelier's principle, the position of equilibrium moves to counteract thechange (more lead cations, common ion), the position of equilibrium will move so that the concentration ofproducts decrease and concentration of reactants of chemical reaction increase.read more on -

This is a solution, hope i could
