WebMass transport in plants is the movement of substances in a single direction and speed. This is seen in the xylem and phloem, transport vessels in plants. The xylem is responsible for transporting water and minerals up the plant via the transpiration stream. The phloem transports amino acids and sugars in both directions: up and down the plant. WebTypically about 90% of the total energy that is available is lost as it passes through a tropic level. There is a formula to calculate net production (all units kJ m -2 yr -1 ): A-level Biology – Transfer of Biomass. Where: N is the net production of the consumer. I is the chemical energy stored in ingested foods.
