UPSC 2003: Assertion (A): Unlike temperate forests, the tropical rain forests, if cleared, can yield productive farm-land that can support intensive agriculture for several years even without chemical fertilizers. Reason (R): The primary productivity of the tropical rain forest is very high when compared to that of the temperate forests.
(a)Both A and R are individually true and R is the correct explanation of A
(b)Both A and R are individually true but R is NOT the correct explanation of A
(c)A is true but R is false
(d)A is false but R is true
Attempt This Question
Not attemptedCorrect Answer: (d) A is false but R is true
Most tropical rainforest soils are heavily leached, acidic and nutrient-poor; once forest cover is removed, fertility declines rapidly and the land supports crops for only a short time, so the assertion is false. The reason is true—tropical rainforests have very high primary productivity due to warm, moist conditions—but high biomass production does not translate into long-term soil fertility after clearing.
