Answer/Explanation:
1. Provisioning of Resources: Ecosystems provide numerous resources like clean water, food, fuel, medicines, and building materials, which are essential for human survival and well-being. These resources are derived from various natural sources within the ecosystem like forests, oceans, wetlands, and rivers. For example, forests provide timber, fuelwood, and non-timber forest products, while oceans provide fish and other seafood.
2. Regulation of Ecosystem Services: Ecosystems provide numerous ecosystem services like water filtration, pollination, carbon sequestration, and climate regulation, which are essential for maintaining the proper functioning of the ecosystem and supporting human well-being. These services are derived from various natural processes within the ecosystem like the hydrological cycle, photosynthesis, and nutrient cycling. For example, wetlands provide water filtration services, while forests provide carbon sequestration services.
