Introduction:
The environment is the natural world around us, consisting of living and non-living things. It is the basic life support system because all living organisms depend on it for survival.

Provision of Essential Resources:
The environment provides essential resources such as air, water, food, and shelter to living organisms. Without these resources, life cannot exist on earth. Oxygen in the air is essential for breathing, water is necessary for hydration and other bodily functions, and food provides the necessary nutrients for growth and development. Shelter protects living organisms from the harsh weather conditions.

Regulation of Climate and Weather:
The environment also regulates the climate and weather patterns on earth. It prevents extreme temperatures, such as excessively hot or cold conditions, which can be detrimental to living organisms. The environment also plays a significant role in preventing natural disasters like floods, hurricanes, and droughts.

Supports Biodiversity:
The environment supports biodiversity, which is essential for the survival of living organisms. Biodiversity refers to the variety of living organisms that exist in an ecosystem. Each organism plays a unique role in the ecosystem, and the loss of one species can have a significant impact on the entire ecosystem.

Recycling of Nutrients:
The environment also recycles nutrients, which is essential for the growth and development of living organisms. For example, decomposers break down dead organisms and convert them into nutrients that can be used by other living organisms.

Conclusion:
In conclusion, the environment is the basic life support system because it provides essential resources, regulates climate and weather patterns, supports biodiversity, and recycles nutrients. Therefore, it is essential to protect and preserve the environment to ensure the survival of living organisms.
