In Class 10, students learn about the environment and its components. The environment refers to everything that surrounds us, including both living and non-living things such as soil, water, animals, and plants. An ecosystem refers to all the living and non-living things present in the environment, and it is a foundation of the Biosphere, which determines the health of the entire planet earth. The components of the environment are mainly divided into two categories: biotic environment and abiotic environment.

• Biotic environment: It includes all living organisms such as animals, birds, forests, insects, reptiles, and microorganisms like algae, bacteria, fungus, viruses, etc. .
• Abiotic environment: It includes all non-living components such as air, cloud, dust, land, mountains, rivers, temperature, humidity, water, water vapor, sand, etc. .

The physical environment is also called the abiotic or non-living environment. It includes soil, water bodies, and air on the surface of the earth, as well as meteorological factors such as sunlight, temperature, rainfall, humidity, pressure, and wind speed.

Human activities have a significant impact on the environment, and it is important for every individual to save and protect our environment. Students learn about the impact of human activities on the environment, including terrestrial ecosystems such as forest, grassland, tundra, and desert ecosystems, as well as aquatic ecosystems such as freshwater.

In summary, the environment class 10 refers to the study of the components of the environment, including both living and non-living things, and their interactions. Students learn about the importance of the environment, the impact of human activities on the environment, and ways to protect and conserve the environment.
