Also to see if the salt water will mix with the fresh water like an estuary when the water mixes with the salt water . Background: Different bodies of water have different amount of salt in this is called different salinities. Salinity is expressed amount of salt in 1000 grams of water. So if there 1 gram of salt in water and 1000 gram of water the salinity would be

The regulation of internal environment by animals: homoeostasis All living organisms have ideal environmental conditions for survival and reproduction. Animals have an internal environment as well as the external environment they are living in. If their internal environment deviates too much from the ideal they may experience reduced function or even die. Homoeostasis is the adapted ability of an organism to regulate its internal environment to deal with changes in the external environment. (Raven

This included Transects‚ Quadrats‚ Salinity and pH Levels‚ and The Temperature of various areas. - A Transect line was used to take a random sample of organisms that occur on the sloping rock on the edge of the rock platform. Organisms generally occupy and dominate specific zones. This

management is the process of managing the use and development of land resources. Over the past few two centuries of exploitation on our land resources‚ has taken a heavy toll on our soils. What are the causes of this issue? e.g land degradation‚ salinity and overgrazing Firstly‚ land degradation is any change in the land that reduces its existing or potential productivity. It commonly occurs wherever the natural balance in the landscape is changed by human activity‚ through misuse or overuse. This

PRACTICAL 3 ECOLOGICAL PATTERNS AND PROCESSES IN MANGROVE ECOSYSTEMS II PROBLEM SET 1. BIOLOGICAL INTERACTION During our Field Trip to the Cairns Airport Mangrove Boardwalk on 7th August‚ 2013‚ I observed a distinct distribution pattern in the locations of the Orange-Clawed Fiddler Crabs (Uca coarctata).

In this study‚ the proponents aimed to establish the effects of Maluggay leaves and seed respectively on seawater. Aside from its potential as biofuel feedstock‚ the seed of moringa‚ locally known as malunggay‚ could also be used for purifying water. Researchers said that seed kernels of malunggay have important amounts of water soluble protein that hold a
