Explanation:

डोडो (रफस क्यूक्यूलैटस) एक विलुप्त उड़ान रहित पक्षी है जो हिंद महासागर में मेडागास्कर के पूर्व मॉरीशस के द्वीप के लिए स्थानिकमारी वाला था। डोडो के सबसे करीबी आनुवांशिक रिश्तेदार भी विलुप्त रोड्रिग्स सॉलिटेयर थे, दोनों कबूतरों और कबूतरों के परिवार की उपपरिवार रफैनी थे। डोडो का सबसे करीबी जीवित रिश्तेदार निकोबार कबूतर है। एक सफेद डोडो को कभी रियूनियन के पास के द्वीप पर मौजूद माना जाता था, लेकिन अब रियूनियन इबिस और सफेद डोडो के चित्रों के आधार पर भ्रम की स्थिति पैदा हो गई है।

सबफॉसिल अवशेष दिखाते हैं कि डोडो लगभग 1 मीटर (3 फीट 3 इंच) लंबा था और जंगली में इसका वजन 10.6–17.5 किलोग्राम (23-39 पाउंड) हो सकता है। जीवन में डोडो की उपस्थिति केवल 17 वीं शताब्दी के चित्र, चित्रों और लिखित खातों से ही स्पष्ट होती है। जैसा कि ये काफी भिन्न होते हैं, और केवल कुछ दृष्टांतों को ज्ञात नमूनों से खींचा गया है, जीवन में इसकी सटीक उपस्थिति अनसुलझी बनी हुई है, और इसके व्यवहार के बारे में बहुत कम लोग जानते हैं। हालांकि डोडो को ऐतिहासिक रूप से मोटा और अनाड़ी माना जाता रहा है, लेकिन अब यह माना जाता है कि इसके पारिस्थितिकी तंत्र के लिए इसे अच्छी तरह से अनुकूलित किया गया है। यह भूरा-भूरे रंग की परत, पीले पैर, पूंछ के पंखों के एक गुच्छे, एक ग्रे, नग्न सिर, और एक काले, पीले और हरे रंग की चोंच के साथ चित्रित किया गया है। यह अपने भोजन को पचाने में मदद करने के लिए गिज़र्ड पत्थरों का इस्तेमाल करता था, जिसके बारे में माना जाता है कि इसमें फल भी शामिल हैं, और माना जाता है कि इसका मुख्य निवास स्थान मॉरीशस के सूखे तटीय क्षेत्रों में जंगल रहा है।

Which of these are the two major sources of nitrate pollution in rivers?
nikklg [1K]

Answer:

The correct answer is <em>c. animal wastes and fertilizers. </em>

Explanation:

Two major sources of nitrate pollution are farming and breeding activities. There are also certain industrial activities involved in nitrate pollution, but in general, these industries are related to agriculture.

The indiscriminate use of fertilizers for several years in intensive productions produce high nitrate concentration in soil and consequently elevate the risk of nitrate lixiviation.

Breeding animals produce nitrate pollution by their wastes, which accumulate and are not treated. These wastes include flesh, hair, feathers, skin, fat, liquids, excrements, among others. These wastes are an important source of nitrate.

In many cases, animal wastes are used by farmers as organic matter to improve their production. But excessive and incorrect use of it might produce severe damage in water sources.
