Class 10 Science Our Environment Quiz Part 1

The environment includes all living and non-living things that interact and sustain life on Earth. It consists of biotic components like plants and animals, and abiotic components like air, water, and soil. Understanding our environment is crucial for maintaining balance and addressing issues like pollution and global warming.

This quiz covers key concepts from “Our Environment,” including ecosystems, food chains, pollution, waste management, and sustainable practices. Test your knowledge on how human actions impact the environment and ways to protect it!
