Extinctions and Disruptions. If one species in the food web ceases to exist, one or more members in the rest of the chain could cease to exist too. A plant or animal doesn't even have to become extinct to affect one of its predators. The harelip sucker fish, for example, used to eat snails in the 19th century.

Afro-Ecuadorian culture may be analysed by considering the two main centers of historical presence: the province of Esmeraldas, and the Chota Valley. Marimba music comes from Esmeraldas, and gets its name from the prominent use of marimbas, along with drums and other instruments specific to this region such as the bombo, the cununo and the wasa. Sometimes this music is played in religious ceremonies, as well as in celebrations and parties. It features call and response chanting along with the music.
