Changes to food chains. If one part of a food chain alters, the whole food chain is affected. For example, if a disease suddenly wiped out caterpillars, it would affect mice, owls and many other animals. Page: 1.
The marimba (/mÉËrÉªmbÉ/) is a percussion instrument consisting of a set of wooden bars struck with mallets to produce musical tones.Resonators attached to the bars amplify their sound.he range of the marimba has been gradually expanding, with companies like Marimba One adding notes up to F above the normal high C (C7) on their 5.5 octave instrument, or marimba tuners adding notes lower than the low C on the 5 octave C2.
In many ways the marimba is like the xylophone although it is pitched an octave lower and produces a richer sound. It is a tuned percussion instrument whose wooden notes are arranged in a similar way to those of the piano.t is a series of wooden bars which vibrate to produce sound when they are hit with a beater. Hanging below the bars are metal tubes of varying lengths, these are called resonators. The metal tubes affect the sound that is produced, amplifying it and making it richer.
