The chapter discusses how the atmosphere, hydrosphere, lithosphere, and biosphere work together to support living organisms and maintain ecological balance.
Natural resources are essential for the survival of all living beings. Air provides oxygen for respiration, water is necessary for life processes, and soil supplies nutrients for plant growth. The chapter explains natural phenomena such as winds, rainfall, the water cycle, and the role of the atmosphere in climate control. It also highlights how these resources are interconnected and continuously recycled through various natural cycles.
The chapter further explains biogeochemical cycles such as the water cycle, carbon cycle, nitrogen cycle, and oxygen cycle, which help maintain balance in nature. It also discusses environmental issues like air pollution, water pollution, soil erosion, global warming, and ozone layer depletion. The chapter emphasizes the need to conserve natural resources and use them sustainably to protect biodiversity and ensure a healthy environment for future generations.
