photosynthetic efficiency वाक्य

With best assumptions for the other numbers, that efficiency range covers everything from a small tree to a really big one-so without knowing the species of tree ( and finding the photosynthetic efficiency of that particular species )-we can't tell what size of tree StuRat would best compare to.
In actuality, however, plants do not absorb all incoming sunlight ( due to reflection, respiration requirements of photosynthesis and the need for optimal solar radiation levels ) and do not convert all harvested energy into biomass, which results in an overall photosynthetic efficiency of 3 to 6 % of total solar radiation.
Assuming an average insolation of 225 W / m 2, the photosynthetic efficiency of sugar cane is 0.38 % . " Sucrose accounts for little more than 30 % of the chemical energy stored in the mature plant; 35 % is in the stem tips, which are left in the fields during harvest, and 35 % are in the fibrous material ( bagasse ) left over from pressing.
