explain the oxygen cycle in nitrogen (in Marathi)
Answers
Answer:
या सर्व प्रक्रिया एकत्र ऑक्सिजन सायकल बनवतात. ... प्रकाशसंश्लेषणाच्या प्रक्रियेद्वारे वनस्पती वातावरणात ऑक्सिजनचे मुख्य निर्माते आहेत. येथे झाड सूर्यप्रकाश आणि कार्बन डाय ऑक्साईडचा वापर ऊर्जा निर्मितीसाठी आणि ऑक्सिजन मुक्त करते. जिराफ ऑक्सिजनमध्ये श्वास घेतो आणि नंतर कार्बन डाय ऑक्साईड बाहेर काढतो.

Answer:
Oxygen Cycle
Oxygen is the second most abundant element in the atmosphere and is present to the extent of about 21 per cent and is essential for all life processes. Atmosphere and oceans are the main pool for oxygen. The oxygen dissolved in water (oceans, etc.) is responsible for sustaining aquatic plants and animals. It is also a constituent of oxide and carbonate ores. There is a continuous exchange of oxygen between the atmosphere and water surfaces of all water bodies. The total amount of oxygen in the biosphere is constant. The oxygen cycle is based on the exchange of oxygen among the segments of the environment, viz., atmosphere, hydrosphere, lithosphere and biosphere. It plays a key role in atmospheric chemistry and life process. The different steps involved in oxygen cycle are:
During respiration, organisms including animals and human beings consume oxygen from the air and give carbon dioxide into the atmosphere.
The green plants utilize carbon dioxide for photosynthesis, in which carbon dioxide reacts with water in presence of solar energy and a catalyst (chlorophyll) to produce carbohydrates and the formed oxygen is released into the atmosphere.
Oxygen is needed by bacteria and fungi during decomposition of organic matter. The products of decomposition (CO2 and H2O) are released into the atmosphere. The released CO2 and H2O are utilised during photosynthesis by green plants.
