Question : The C_4 plants are twice as efficient as C_3 plants in terms of fixing CO_2 but lose only ... as much water C_3 plants for the same amount of CO_2 fixed.

Question : The C_4 plants are twice as efficient as C_3 plants in term

1.	Question : The C_4 plants are twice as efficient as C_3 plants in terms of fixing CO_2 but lose only ... as much water C_3 plants for the same amount of CO_2 fixed.
Answer» Solution :HALF (less of WATER). The work efficiency of `C_4` is as such that in which `CO_2` FIXATION BECOMES maximum. The water loss in its comparisons less (half). `C_4` plants fix `CO_2` and POSSESS double work efficiency than `C_3` in formation of Glucose. But during equal `CO_2` fixation loses water half than`C_3`.
