← Nature & AnimalsWhich growth impediment emerges when C4 photosynthesis underperforms?
A)Accelerated leaf water loss
B)Inhibition of photorespiration fixation
C)Depleted soil ammonium uptake
D)Inefficient carbon reallocation overhead✓
💡 Explanation
The consequence involves diminished growth because, without the C4 pathway’s increased efficiency to deliver concentrated CO2 to Rubisco, the carbon reallocation overhead for futile cycles becomes inefficient; therefore C4 plants require more resources rather than optimal gain without the pathway.
