The word symbiosis refers to this partnership.<\/li><li>The first statement is true. The invertebrate class Cnidaria frequently has a symbiotic relationship with the single-celled dinoflagellate algae known as zooxanthellae.<\/li><li>The second claim is true. Some fungi are found living inside plant roots. The fungus receives nutrients from the plants in exchange for water and specific nutrients from the plants. Algae and fungi coexist as lichen in a symbiotic relationship.<\/li><li>The third statement is true. Additionally, protozoa develop symbiotic relationships with other creatures. Protozoan symbiosis mainly includes: a strong mutualistic relationship between a protozoan and a single-celled symbiont (such as bacteria, cyanobacteria, or single-celled algae), or between a protozoan and a multicellular organism (ruminants, lower termites, wood-eating cockroaches, plants)<\/li><\/ul>\n\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.
