They secrete acids that help weather the rock, breaking it down and creating initial soil particles, which allows other plants to eventually grow. They are also excellent indicators of air quality because they are very sensitive to atmospheric pollution.<\/section>\n","protected":false},"excerpt":{"rendered":"<p>Lichens, which are capable of initiating ecological succession even on a bare rock, are actually a symbiotic association of [amp_mcq option1=&#8221;algae and bacteria&#8221; option2=&#8221;algae and fungi&#8221; option3=&#8221;bacteria and fungi&#8221; option4=&#8221;fungi and mosses&#8221; correct=&#8221;option2&#8243;] This question was previously asked in UPSC IAS &#8211; 2014 Download PDFAttempt Online Lichens are a symbiotic association between a fungus and &#8230; <\/p>\n<p class=\"read-more-container\"><a title=\"Lichens, which are capable of initiating ecological succession even on\" class=\"read-more button\" href=\"https:\/\/exam.pscnotes.com\/mcq\/lichens-which-are-capable-of-initiating-ecological-succession-even-on\/#more-91161\">Detailed Solution<span class=\"screen-reader-text\">Lichens, which are capable of initiating ecological succession even on<\/span><\/a><\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1092],"tags":[1468,1117,1115],"class_list":["post-91161","post","type-post","status-publish","format-standard","hentry","category-upsc-ias","tag-1468","tag-biology","tag-miscellaneous","no-featured-image-padding"],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v22.2 (Yoast SEO v23.3) - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>Lichens, which are capable of initiating ecological succession even on<\/title>\n<meta name=\"description\" content=\"Lichens are a symbiotic association between a fungus and a photosynthetic organism, typically an alga or a cyanobacterium.
