Effects of motor oil on freshwater algae

Marcus Clewis

INTRODUCTION

Algae is an organism that contributes a whole variety of different types of phylogenetic groups. Some scientist refer to the algae as a plant: due to its way of feeding from suns energy. While getting energy from the sun algae must stand in a stationary location where there a source of water and cool humidity. Algae can survive on a rock, depending on how close the rock is from the nearby water source. Algae can only stand the substance of managing water source. No algae can carry its process in areas where there is dry land.

In the matter of harm and death; algae can be harmful to other species. An article excluded a matter of the problem (fish kills). E.P.A's National Coastal Condition Report (National Center For Environmental Research, 2010) observed that due to beaches being ; no swimming and dead fishes. Is coming at fault of the amount of the algae in the water causing fishes to lose oxygen. This is a deed of an problem for the city of San Francisco. In the case of E.P.A's investigation, San Francisco is a hot spot for eutrophication. Algae itself, depending on type of organism it is.

In the world, there are all types of algae living within local creeks, lakes, reservoirs, and along the world's two biggest oceans: the Pacific Ocean and the Atlantic Ocean. About eleven different types of algae. Fuzz algae, grows on plants and is measured up to (2-3mm) fo strands. Identified as a beard. The fuzz algae is controlled by a algae eater called the Black mollies. Beard algae, can mostly grow around anything such as a fish tank. Its strands brings out a bright green and very fine texture that can grow and bring together a huge colony of beard algae. Another that most common is the blue green algae , that can be found all over nearby creeks and lakes. It can grow rapidly amongst everything that it can get closer to. The blue green algae can also be a indication for causing pure quality water to unqualified poor water. This what causes fish kills amongst local beaches such as the case in San Francisco.

Keep note that not all algae endure the same threat. Algae that are among small quantities manage well in pure water. Algae that have huge out going school of algae can drill a impact of creating a pure source of water to a bad one. Algae can usually can be located in huge bodies of water. Also in some cases algae can found in the snow. Scientist name Ron Hoham and few other scientist found out that algae have an microscopic organism that can survive in places where it's mostly chilly. William and other scientific colleagues from the national academy of science found out that snow algae can absorb via photosynthesis and carbon dioxide more than a rate of one -tenth oppose to average plant.

Stating the information coming from www.ehow.com an article by S.F. Heron, an ehow.com contributing writer. He explains how oil spreads and stretches across the water surface. Heron talked about how when oil is spilled into the water, it's its own brand of liquid that floats on top of the surface of the water. It is a short period of time where the oil is beginning to spread across the surfaces and starting to causing a great deed of chaos amongst plants and animals. Different types of oil when spilled has different cause and affects. Some types involve in small amounts of oil when other types will start to break apart in quick amounts of oil. Searching www.fws.gov on the "effects of oil on wildlife and habitat". Algae in local marines, are more frequently coming across spilled oil. Killing a lot of marine creatures. Algae can die and become abundant to spilled oil. But the oil spills can bring the stop towards growing plants.

An algal physiologist named J.H. Vandeermeulen (SOURCE) explained on how there are ships with huge amount of oil are being spilled into the water surfaces. Whole oils retard the growth of algae and petroleum hydrocarbons reduce the rate of photosynthesis.
With the affection from the oil coming against the growth of algae is one of the reason as to why there are fish kills in some areas around the country.

Make sure that you are citing your references in the appropriate parts of the text, using the last name and year of publication in parentheses — for example, (Smits 2008).

Now that you've set up the big picture and some specific context information, explain the purpose of your current experiment and your rationale for doing the experiment this way.

METHODS

I made a trip to Dimond Park to collect my algae from the nearby creeks leading up to the Diablo Range of the Oakland hills (refer to FIG.1) A lot of bush algae was found on the nearby rocks connected to the creeks and algae inside the creek. A sample of algae was collected in a water bottle using a pair of gloves. Five different samples were created. The five water bottles with algae was exposed to sunlight wherever it was transported. At Arise high school, drops of motor oil was put into each 200-mL water bottle with algae, 0 drops, 5 drops, 10 drops, 20 drops, and 50 drops, in each water bottle respectively. The status of the algae was observed a week later.

Where is Figure 1?

RESULTS

A week later, no significant physical change was seen in the algae. However, a type of insect larvae found in every water bottle died within two days of exposing them to motor oil. It is possible that the larvae died because the motor oil cut off their oxygen supply. The algae may have survived because despite the presence of oil, they were still able to take in the sunlight needed for respiration.

DISCUSSION

Future studies: seeing the affects of motor oil on aquatic specimens. I could have waited longer to see the effect of oil on algae. My possible explanation for the matter of oil, is that motor oil would only be purified when its only up to 100 percent to make a possible impact on the algae, to see a reaction. Crude oil might do the good by causing a reaction to the algae, due to its mixture of kind of chemicals that are combined to make the crude oil. For the future possibility of researching I wonder if there are other types of algae that can be more resistant to oil and what type of algae can respond quickly to motor oil?
