The catfish‚ on the other hand‚ has taste buds all over its body to help it sense food and scan large areas of food. 3. Explain how a freshwater fish maintains osmotic balance. In a freshwater fish‚ the inside of the fish’s body has a higher concentration of salt than the external environment. To prevent loss of water‚ fish have very efficient kidneys that excrete water quickly. The kidneys also reabsorb salt from

It is vital and with the most urgency that this natural resource is taken care of and maintained responsibly because planet earth depends on freshwater to survive and if our natural resources aren’t reasonably maintained and allowed to be depleted

PART (1) Ellen Ryan Introduction This experiment was carried out in order to better understand Hong Kong’s ecology and biodiversity‚ specifically focusing on field-based whole organism biology in an area with little human interferences. Method 1. Lay a horizontal transect on the mid-shore (1.75m) 2. Repeat for high-shore (2.25m) 3. At regular intervals of 1m

In the great state of Utah‚ there are many ecosystems that work together in order to create this wonderful state. Utah has many aquatic ecosystems to include: the Great Salt Lake‚ Utah Lake and the northern river otter to name a few. Utah also has the Rocky Mountains‚ which are a terrestrial type ecosystem‚ these two ecosystems are just the tip of the iceberg when it comes to Utah’s greatest areas. Utah is home to many gorgeous areas to explore‚ the focus of this paper will be on the Utah Lake

decade as a result of a building boom for new homes‚ hotels‚ and resorts. The increase in water demand has resulted in the disruption of past sustainable water management practices. At present‚ most freshwater needs are met through the use of the limited groundwater‚ desalinated seawater‚ and freshwater importation. Wastewater reclamation‚ not used extensively‚ can serve as an alternative source of water‚ for a variety of applications now served with desalinated and imported water. Three alternative
