Show answer & explanation
Correct answer: D. A, B, C and DA, B, C और D
Explanation
Wetlands, oceans and soil are the standard natural carbon sinks: peat and marsh sediments lock up organic carbon, the oceans dissolve CO₂ and store it in the deep water, and soil organic matter holds a large carbon pool. The key also counts elephants, since carbon is stored in their biomass and forest elephants measurably raise the carbon stock of the forests they shape. Hence A, B, C and D.आर्द्रभूमियाँ, महासागर और मृदा मानक प्राकृतिक कार्बन सिंक हैं: पीट एवं दलदली अवसाद कार्बनिक कार्बन को रोक लेते हैं, महासागर CO₂ को घोलकर गहरे जल में संचित करते हैं तथा मृदा कार्बनिक पदार्थ में विशाल कार्बन भंडार रहता है। कुंजी हाथियों को भी सम्मिलित करती है, क्योंकि उनके जैवभार में कार्बन संचित रहता है और वन-हाथी जिन वनों को आकार देते हैं उनका कार्बन भंडार मापनीय रूप से बढ़ाते हैं। अतः A, B, C और D।More People, Development and Environment questions
