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.
This grouped ecosystem services into four broad categories: provisioning, such as the production of food and water; regulating, such as the control of climate and disease; supporting, such as nutrient cycles and crop pollination; and cultural, such as spiritual and recreational benefits.
