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.
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.
The instrument is traditionally played with a variety of mallets, but the hardest mallets are avoided so as not to risk cracking the bars. An instrument called the xylorimba, or sometimes the xylo-marimba or marimba-xylophone, is a type of xylophone with a range that extends down into that of the marimba.he marimba is a truly beautiful instrument and it has been used in a remarkable range of music. I think for me the most interesting use has been in the looping music of various minimalist composers. The flat tone and percussive elements of the marimba make it uniquely suited to create hypnotic, droning patterns.
