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.
Tropical rainforests are not my study area, but I know a little bit about this topic from reading. Obviously, tropical rainforests are very rainy. So, water is not a limiting factor in this ecosystem, at least to many of the organisms. Water might be more limiting to epiphytes, plants that live on other plants and don't have access to water in the soils.
