Fungi. <br\/>\n<strong>Explanation:<\/strong> Mycoremediation is a form of bioremediation that uses fungi, particularly their mycelium, to absorb and break down pollutants. Fungi produce powerful enzymes capable of decomposing complex organic pollutants, such as petroleum and pesticides.\n<\/div>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">Q3.
