A phenomenon where worker bees disappear suddenly, leaving behind the queen and young bees. <br\/>\n<strong>Explanation:<\/strong> Colony Collapse Disorder (CCD) is a phenomenon where a large number of worker bees suddenly vanish from a beehive, leaving behind the queen, immature bees (brood), and adequate food supply like honey and pollen. This sudden disappearance weakens the colony, making it unsustainable. The exact cause is unknown, but multiple factors contribute to it, and without worker bees, the hive collapses over time.\n\n<\/div>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">Q2. Which of the following is NOT a likely cause of CCD?<\/h3>\n\n\n\n<ol class=\"wp-block-list\">\n<li style=\"font-size:17px\">Overpopulation of bees in the hive<\/li>\n\n\n\n<li style=\"font-size:17px\">Pesticide exposure<\/li>\n\n\n\n<li style=\"font-size:17px\">Varroa mite<\/li>\n\n\n\n<li style=\"font-size:17px\">Malnutrition<\/li>\n<\/ol>\n\n\n\n<button class=\"acc\">View Answer<\/button>\n<div class=\"pnl\">\n  <p style=\"padding-top:5px;color:#27302a;font-size:1.2rem;\"><b>Correct Option:<\/b> 1. Overpopulation of bees in the hive. <br\/>\n<strong>Explanation:<\/strong> While CCD has several known contributing factors\u2014such as parasitic mites (like Varroa), exposure to harmful pesticides, and nutritional deficiencies due to poor-quality food replacements\u2014overpopulation is not one of them. In fact, stronger, populous hives are often more resilient. CCD is primarily characterized by a weakening or sudden loss of worker bees, not by overcrowding.\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. Why are neonicotinoids considered dangerous for bees?<\/h3>\n\n\n\n<ol class=\"wp-block-list\">\n<li style=\"font-size:17px\">They kill bees on direct contact<\/li>\n\n\n\n<li style=\"font-size:17px\">They confuse bees and affect their ability to return to the hive<\/li>\n\n\n\n<li style=\"font-size:17px\">They increase bee fertility and overcrowd hives<\/li>\n\n\n\n<li style=\"font-size:17px\">They make nectar taste bitter<\/li>\n<\/ol>\n\n\n\n<button class=\"acc\">View Answer<\/button>\n<div class=\"pnl\">\n  <p style=\"padding-top:5px;color:#27302a;font-size:1.2rem;\"><b>Correct Option:<\/b> 2. They confuse bees and affect their ability to return to the hive. <br\/>\n<strong>Explanation:<\/strong> Neonicotinoids are a class of insecticides that act on the nervous systems of insects. Bees exposed to these chemicals\u2014often through pollen or nectar\u2014may not die immediately but suffer from sublethal effects. These include impaired memory, learning, and navigation, making it difficult for them to return to the hive. This contributes significantly to the CCD phenomenon.\n<\/div>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">Q4. What role do bees play in agriculture?<\/h3>\n\n\n\n<ol class=\"wp-block-list\">\n<li style=\"font-size:17px\">They aerate the soil<\/li>\n\n\n\n<li style=\"font-size:17px\">They spread plant diseases<\/li>\n\n\n\n<li style=\"font-size:17px\">They pollinate crops, aiding food production<\/li>\n\n\n\n<li style=\"font-size:17px\">They protect plants from pests<\/li>\n<\/ol>\n\n\n\n<button class=\"acc\">View Answer<\/button>\n<div class=\"pnl\">\n  <p style=\"padding-top:5px;color:#27302a;font-size:1.2rem;\"><b>Correct Option:<\/b> 3. They pollinate crops, aiding food production. <br\/>\n<strong>Explanation:<\/strong> Bees are among the most effective pollinators in nature. When they collect nectar, they also carry pollen from one flower to another, enabling cross-pollination. This process is essential for the reproduction of many plants and crops. Without bees, at least 30% of the world\u2019s food crops and 90% of wild plants would be at risk of reduced growth and reproduction, seriously threatening global food security.\n<\/div>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">Q5.
