An example of homophonic music would be melody and accompaniment. Someone singing a melody and a guitar accompaniing them. In this case the singer's melody would be the predominate layer of sound. A concerto is an example of homophony in classical music. A solo is played with an orchestra accompianing. Homophony refers to the texture of a piece of music. It means that there are two or more parts that move together in harmony to create chords. An example would be a typical four-part hymn. This is the opposite of polyphony, where each part moves independently (as in a Bach fugue).
Ecosystem approach. 1  The ecosystem approach is a strategy for the integrated management of land, water and living resources that promotes conservation and sustainable use in an equitable way. 2  An ecosystem approach to agriculture and natural resource management explicitly identifies opportunities and trade-offs. It can preserve or increase the capacity of an ecosystem to produce benefits for the society, fairly apportions benefits and costs, and is sustainable over the longer-term.
Humankind benefits in a multitude of ways from ecosystems. Collectively, these benefits are becoming known as ecosystem services. Ecosystem services are regularly involved in the provisioning of clean drinking water and the decomposition of wastes.
