Assertion: Soil is the most important renewable natural resource.
Reason: Soil supports different types of living organisms on earth.
Explanation:
Soil is indeed the most important renewable natural resource due to its vital role in supporting various forms of life on Earth. Let's break down the given assertion and reason to understand why option A is the correct answer.
Importance of Soil:
1. Food Production: Soil provides essential nutrients, water, and support for the growth of plants. It is the foundation for agriculture and plays a crucial role in food production. Without fertile soil, it would be difficult to sustain a growing population.
2. Habitat for Living Organisms: Soil serves as a habitat for numerous organisms, including bacteria, fungi, insects, worms, and plant roots. These organisms contribute to the overall health and fertility of the soil. They also help in nutrient cycling and decomposition, which further supports the growth of plants.
3. Water Filtration: Soil acts as a natural filter for rainwater and groundwater. It helps in the purification process by removing impurities and pollutants, preventing them from reaching water bodies and underground aquifers.
4. Nutrient Cycling: Soil plays a crucial role in nutrient cycling. It acts as a reservoir for essential nutrients like nitrogen, phosphorus, and potassium, which are necessary for plant growth. The decomposition of organic matter in the soil releases these nutrients, making them available to plants.
5. Carbon Sequestration: Soil has the ability to store carbon, thereby helping in mitigating climate change. When organic matter decomposes in the soil, carbon is stored in the form of humus. This process, known as carbon sequestration, helps in reducing the amount of carbon dioxide in the atmosphere.
Explanation of the Reason:
The reason provided in the statement is correct. Soil supports different types of living organisms on Earth. It provides a habitat for microorganisms, insects, worms, and plant roots. These organisms contribute to the overall health and fertility of the soil. They help in nutrient cycling, decomposition, and maintaining the ecological balance.
Conclusion:
From the above explanation, it is clear that both the assertion and reason are true, and the reason correctly explains the assertion. Hence, the correct option is A. Soil is indeed the most important renewable natural resource as it supports different types of living organisms on Earth and plays a crucial role in various ecological processes.
