In addition, the hoseâs volume fluctuation decreases the hydraulic system reaction time and efficiency. By comparison, the expansion of metal tube is negligible, which makes it a preferred choice for applications requiring accurate positioning.
Aquatic Ecosystems. Most aquatic ecosystems are limited by salt concentration and the availability of sunlight, oxygen and nutrients. For example The Dead Sea is âdeadâ because the salinity is so high and nothing can grow in it.
Aquatic Ecosystems An aquatic ecosystem is an ecosystem located in a body of water. It comprises aquatic fauna, flora and the properties of water too. There are two types of aquatic ecosystems, Marine and freshwater.The Marine Ecosystem. Marine ecosystems are the largest ecosystems with coverage of nearly 71% of the Earth's surface and containing 97% of the planet's water. The water in Marine ecosystems has salts and minerals dissolved in them in high amounts.hese are the ecosystems where abundance of flora (plants) is seen and they have a large number of organisms living in relatively small areas. Therefore, the density of life in forest ecosystems is very high. Any small change in the ecosystem can affect the whole balance and collapse the ecosystem.
