Which principle states that two closely related species competing for the same resources cannot coexist indefinitely ?
कौन-सा सिद्धांत कहता है कि एक ही संसाधनों के लिए प्रतिस्पर्धा करने वाली दो निकट संबंधी प्रजातियाँ अनिश्चित काल तक साथ नहीं रह सकती हैं?
Detailed Solution & Logic
Gause's Rule/गाउस का नियम
Explanation / व्याख्या:
Gause's Rule, also known as the Competitive Exclusion Principle, states that two closely related species competing for the same limited resources cannot coexist indefinitely in the same ecological niche. One species will eventually outcompete and exclude the other.
गाउस का नियम (Competitive Exclusion Principle) के अनुसार, यदि दो निकट संबंधी प्रजातियाँ एक ही सीमित संसाधन के लिए प्रतिस्पर्धा करती हैं, तो वे एक ही पारिस्थितिक निच (Ecological Niche) में अनिश्चित काल तक साथ नहीं रह सकतीं। अंततः एक प्रजाति दूसरी को प्रतिस्पर्धा में हरा देगी।
This principle was proposed by Georgy Gause, a Russian biologist, based on experiments with microorganisms.
यह सिद्धांत रूसी जीवविज्ञानी Georgy Gause द्वारा सूक्ष्मजीवों पर किए गए प्रयोगों के आधार पर प्रस्तुत किया गया था।
Extra Facts / अतिरिक्त तथ्य
The Competitive Exclusion Principle is a fundamental concept in Ecology.
प्रतिस्पर्धी बहिष्करण सिद्धांत पारिस्थितिकी (Ecology) का एक महत्वपूर्ण सिद्धांत है।
Species can coexist if they undergo resource partitioning, meaning they use resources in different ways or at different times.
प्रजातियाँ साथ रह सकती हैं यदि वे संसाधन विभाजन (Resource Partitioning) अपनाएँ, अर्थात संसाधनों का उपयोग अलग-अलग तरीकों या समय पर करें।
Gause demonstrated this principle using two species of Paramecium.
गाउस ने इस सिद्धांत को Paramecium की दो प्रजातियों पर प्रयोग करके सिद्ध किया था।
This principle helps explain biodiversity, species distribution, and ecosystem structure.
यह सिद्धांत जैव विविधता, प्रजातियों के वितरण और पारिस्थितिक तंत्र की संरचना को समझने में सहायता करता है।
