Sample Questions :
TASK 1:
Construct a concept map on this topic using the mind map software. Safe the file in the followings format: pdf, image files (jpg, png) OR copy the URL in WORD and submit in the ASSIGNMENT (Concept Map of Marine and Fresh Water) in PutraLMS.
TASK2: Answer the following questions and save the file under your name and submit to the ASSIGNMENT in PutraLMS.
A. FILL IN THE BLANK
1. Partially enclosed coastal regions where a river meets the sea called estuaries have a characteristic salinity profile called a salt wedges where freshwater floats on denser saltwater. 2. When nutrients are added to a lake, it can become eutrophic (nutrient rich) and this can degrade the quality of the lake. 3. Lakes can be thermally stratified. The warm upper layer is called the epilimnion, and the deeper colder layer is called the hypolimnion. These two are separated by a zone of rapid temperature decrease called the Thermocline. 4. If the amount of organic material added to a river or stream is not excessive, algae grow and produce oxygen during the day. At night, the oxygen is consumed, resulting in diurnal oxygen shifts. 5. Aquatic environments are termed low-oxygen diffusion environments because oxygen diffuses slowly through water. Furthermore, the solubility of oxygen in water is limited. This can lead to the formation of hypoxic (low oxygen levels) and anoxic (oxygen-free) zones, which allow specialized microorganisms to grow. 6. Photosynthetic microbes and small plants suspended in water are called phytoplankton. They create organic matter that enters the
microbial loop, a complex process that cycles organic 12
matter from dissolved forms to particulate forms and then back to carbon dioxide and other materials. 7. To supplement ATP production, some microbes in the oligotrophic ocean areas use proteorhodopsin in the same way that archaea use bacteriorhodopsin. Other bacteria will use aerobic anoxygenic phototrophy, although it is not true photosynthesis since carbon is not fixed. Others acquire energy from inorganic compounds while using organic carbon sources in the process of lithoheterotrophy. 8. Lakes vary in nutrient status. Some are oligotrophic (nutrient poor) and some are eutrophic (nutrient rich). 9. The release of inadequately treated wastes and other materials at a single location on a river or stream is a type of point source pollution. Runoff from fields and feedlots is a type of non point source pollution.
