A biodome is a controlled, enclosed environment that replicates natural ecosystems. It is designed to support various forms of life, including plants, animals, and microorganisms. Biodomes often feature climate control systems to maintain temperature, humidity, and light levels, allowing researchers to study ecological interactions and sustainability. These structures can serve educational purposes, showcasing biodiversity and environmental conservation. One famous example is the Montreal Biodome in Canada, which simulates different ecosystems, such as a tropical rainforest and a polar environment. Biodomes contribute to scientific research and public awareness about the importance of preserving our planet's ecosystems.
