Animals that eat the remains of other animals are called scavengers. They include creatures such as Tasmanian devils and vultures. Organisms (meaning both plants and anima â¦ ls) that eat the remains of other plants and animals are known as detritivores. These animals break down dead organic matter and feed on it, thereby returning nutrients to he ecosystem.
From Wikipedia, the free encyclopedia. Gneiss /ËnaÉªs/ is a common and widely distributed type of rock formed by high-grade regional metamorphic processes from pre-existing formations that were originally either igneous or sedimentary rocks. It is often foliated (composed of layers of sheet-like planar structures).
Gneiss rock is further characterized by its alternating light and dark bands of minerals. Gneiss forms from volcanic rock, shale, or granitic. Quartz is typically abundantly found in gneiss. The bands that form on gneiss rock are due to the various rocks that are a part of its make-up. The use of the word gneiss dates back to the mid-1700s. Gneiss rocks that originate as sedimentary rock are called paragneiss and those originating as igneous rock are called orthogneiss. Limestone can change into calcareous gneiss which contains calcium carbonate.
