Given below are two statements. In the light of the above statements, choose the correct answer from the options given below.
Statement I:An increase in CO2 is expected to enhance global plant growth.
Statement II:Deforestation can increase the biosphere's capacity.
ABoth Statement I and Statement II are true
BBoth Statement I and Statement II are false
CStatement I is true but Statement II is false ✓ Correct
DStatement I is false but Statement II is true
Correct answer: (C) Statement I is true but Statement II is false
Explanation
Higher carbon dioxide can boost photosynthesis and enhance global plant growth in many species.
Statement 1 describing this carbon dioxide fertilization effect is accurate.
Deforestation removes trees that store carbon and support life, cutting the biosphere's capacity.
Statement 2 claiming deforestation increases the biosphere's capacity is false.
Losing forests reduces carbon uptake and weakens the land carbon sink instead.
The fertilization gain is also limited by water, nutrients and rising heat stress.
