Biodiversity forms the basis for human Existence in the following ways : 1. Soil formation 2. Prevention of soil erosion. 3. Recycling of waste 4. Pollination of crops Select the correct answer using thew codes given below :

Biodiversity is fundamental to human existence by providing essential ecosystem services. It plays a critical role in soil formation through the biological activities of soil organisms that facilitate weathering and nutrient fixing [1]. Biodiversity prevents soil erosion by maintaining forest cover and increasing soil stability through organic matter that binds particles together [1]. Furthermore, it is vital for the recycling of waste, where microorganisms and soil biota decompose organic matter and pollutants, effectively cleansing the environment [1]. Finally, biodiversity is indispensable for the pollination of crops, a service performed by diverse insects and animals that ensures global food security and agricultural productivity. These processes collectively underpin the supporting and regulating services necessary for sustaining life on Earth [1].
