1m cubed of a field gets about 1050Mj of light energy per year.
only 21 500kJ of energy is stored in the new grass.
(i) How is the energy stored in the new grass?
...............................................................................
(ii) What is the % of light energy stored in the grass?

This should go to the biology section instead of the math section.
i. Photosynthesis
ii. 21500/1050000

There is a vast diference in the amount of energy the area of the soil receives and the amount stored in the grass that is grown. This is because most of the energy is used for other purpose like, evaporation of water, heating the soil, and in the environment around. so, only a part of it is used by the plant for its use...
% of light energy stored in the grass=(21500/1050000)*100%=2.047%

i. It is stored in the chemical bonds that were created when the raw materials were turned into the constituents of the grass e.g. cellulose.
ii. 21,500 kJ / 1,050,000 kJ = 2.05% (to 2 sig figs)

the energy is stored in the new gfrass by photosynthesis aint it. n the % of wat is stored is watever the grass dont use at the time. lol . was i even close?
