An ecosystem is a community made up of living organisms and nonliving components such as air, water, and mineral soil. Ecosystems can be studied in two different ways. They can be thought of as interdependent collections of plants and animals, or as structured systems and communities governed by general rules. The living (biotic) and non-living (abiotic) components interact through nutrient cycles and energy flows. Ecosystems include interactions among organisms, and between organisms and their environment. Ecosystems can be of any size but each ecosystem has a specific, limited space. Some scientists view the entire planet as one ecosystem.
Ecosystem services are the benefits that human beings get from nature. Using an ecosystem service-based approach can increase agricultural productivity and strengthen the resilience of rural communities and their natural resource base.
