It discusses different levels of biodiversity, including <strong>genetic diversity, species diversity, and ecosystem diversity<\/strong>. The chapter also highlights the causes of biodiversity loss such as habitat destruction, pollution, climate change, and overexploitation of resources. In addition, it explains the importance of conservation through methods like <strong>in-situ conservation (national parks, wildlife sanctuaries, biosphere reserves)<\/strong> and <strong>ex-situ conservation (zoos, botanical gardens, seed banks)<\/strong>. Understanding biodiversity and conservation helps promote sustainable development and protect natural ecosystems for future generations.These concepts are important for both Class 12 board exams and
