Sap activity, which transforms excess ingested sugar into long-chain oligosaccharides." A much larger set of animals do however consume phloem sap by proxy, either "through feeding on the honeydew of phloem-feeding hemipterans. Honeydew is physiologically less extreme than phloem sap, with a higher essential:non-essential amino acid ratio and lower osmotic pressure," or by feeding on the biomass of insects that have grown on more direct ingestion of phloem sap. Maple syrup is made from reduced sugar maple xylem sap. The sap often is harvested from the Sugar Maple, "Acer saccharum". In some countries (e.g., Lithuania, Latvia, Estonia, Finland, Belarus, Russia) harvesting
Sugary drink tax subsidize healthier foods like fruits and vegetables. The imposition of a sugar tax means that sellers of sugary drinks would have to increase the price of their goods by an amount P2 from the original price X, and then take on the rest of the tax themselves (P1) in the form of lower profit per unit sold. The tax burden on consumers (P2) makes it more expensive for consumers to buy sugary drinks and hence a higher proportion of their incomes would have to be spent to buy the same amount of sugary drinks. This decreases the equilibrium quantity of
