One species lives only in tree holes; another species lives only in streams. What sort of barrier exists between these two species?

ایک نوع صرف درختوں کے سوراخوں میں رہتی ہے۔ دوسری نسل صرف ندیوں میں رہتی ہے۔ ان دو پرجاتیوں کے درمیان کس قسم کی رکاوٹ موجود ہے؟
Explanation
  • A habitat barrier exists because the two species occupy different environments (tree holes vs. streams).
  • This prevents them from interacting and reproducing, leading to reproductive isolation.
