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 sugary drinks that will be sold. Whether the sugary drinks tax is imposed on the seller or consumer, in both cases the tax burden is shared between both. The way that the tax burden is divided upon the consumer and seller depends on the price elasticity for sugary drinks. The tax burden will fall more on sellers when the price elasticity of demand is greater than the price elasticity of supply while on buyers when the price elasticity of supply is greater than the price elasticity of demand. The price elasticity for sugary drinks is different from country to country.
