- A.Ecological Biodiversity
- B.Laws of limiting factor
- C.Species area relationships✓
- D.Population Growth equation
Correct Answer
(C) Species area relationships
Solution & Explanation
Answer: (C) Species area relationships. Solution: NCERT credits the German naturalist and geographer Alexander von Humboldt with first observing that within a region species richness increases with explored area up to a limit—the species-area relationship. He is not associated with the laws of limiting factor or the population growth equation, and 'ecological biodiversity' is not the term he introduced, so the other options are incorrect. NCERT: NCERT Class XII Biology, Ch 13 Biodiversity and Conservation, p.220, lines 11–16: "the great German naturalist and geographer Alexander von Humboldt observed that within a region species richness increased with increasing explored area, but only up to a limit."
