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.
There two types of aquatic biome, the marine regions, and the freshwater regions. The marine regions The marine regions are divided between coral reefs, estuaries, and oceans. Oceans represent the largest and most diverse of the ecosystems; salt water evaporates and turns to rain which falls on the land regions, while most of the oxygen in our atmosphere is generated by algae.
