Here, the main reservoir of nutrients is the atmosphere or the hydrosphere. In the sulfur cycle, the nutrient is released by the weathering of rocks, erosional runoff and decomposition of organic matter. The sulphur cycle is mostly sedimentary but two of its compounds hydrogen sulfide (H2S) and sulphur dioxide (SO2) add a gaseous component to its normal sedimentary cycle.<\/li><li>In the Phosphorus cycle, nutrients are released mainly by weathering of rocks since the Phosphorus mainly occurs as a mineral in phosphate rocks. It enters the cycle of erosion and mining activities<\/li><\/ul>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" width=\"338\" height=\"548\" data-src=\"https:\/\/edukemy.com\/blog\/wp-content\/uploads\/2024\/02\/image-40.png\" alt=\"\" class=\"wp-image-30200 lazyload\" src=\"data:image\/gif;base64,R0lGODlhAQABAAAAACH5BAEKAAEALAAAAAABAAEAAAICTAEAOw==\" style=\"--smush-placeholder-width: 338px; --smush-placeholder-aspect-ratio: 338\/548;\" \/><\/figure><\/div>\n\n\n<figure class=\"wp-block-image size-full\"><a href=\"https:\/\/edukemy.com\/free-resources-for-upsc?utm_source=Blog&amp;utm_medium=Banner&amp;utm_campaign=Resources\" target=\"_blank\" rel=\"noreferrer noopener\"><img decoding=\"async\" width=\"1280\" height=\"300\" data-src=\"https:\/\/edukemy.com\/blog\/wp-content\/uploads\/2024\/06\/18.png\" alt=\"\" class=\"wp-image-42398 lazyload\" data-srcset=\"https:\/\/edukemy.com\/blog\/wp-content\/uploads\/2024\/06\/18.png 1280w, https:\/\/edukemy.com\/blog\/wp-content\/uploads\/2024\/06\/18-1170x274.png 1170w, https:\/\/edukemy.com\/blog\/wp-content\/uploads\/2024\/06\/18-585x137.png 585w\" data-sizes=\"(max-width: 1280px) 100vw, 1280px\" src=\"data:image\/gif;base64,R0lGODlhAQABAAAAACH5BAEKAAEALAAAAAABAAEAAAICTAEAOw==\" style=\"--smush-placeholder-width: 1280px; --smush-placeholder-aspect-ratio: 1280\/300;\" \/><\/a><\/figure>\n\n\n\n<p>For UPSC Prelims Resources,&nbsp;<a href=\"https:\/\/edukemy.com\/upsc-cse-prelims-resource-centre\" target=\"_blank\" rel=\"noreferrer noopener\">Click here<\/a><\/p>\n\n\n\n<p>For Daily Updates and Study Material:<\/p>\n\n\n\n<p>Join our Telegram Channel \u2013&nbsp;<a href=\"https:\/\/t.me\/WithEdukemy4IAS\" target=\"_blank\" rel=\"noreferrer noopener\">Edukemy for IAS<\/a><\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>1.
