The Port Kamala Rock Platform Essay

Introduction Last week, my Biology class and I went down to the Port Kamala Rock Platform. While we were there we surveyed five different sectors about the rock platform and recorded them, these included: 1 . Surveying the biotic characteristics of the rock platform 2. Observing the abundance and distribution of the Black Periwinkle (Inertia Tournaments) 3. Observing the feeding relationships and food webs of the organisms 4. Finding the adoption’s of organisms 5. And Observing the human impacts We then filled in all of our work sheets and went back to class to discuss everyone’s exults.

Aims For our first sector our aim was to measure all the biotic characteristics of the rock platform. In the second sector we were finding the distribution and abundance of the black Periwinkle. For our third sector our aim was to observe the feeding relationships and food webs of the organisms. For the fourth sector we had to find the adoption’s of some of the marine life. And for the fifth sector, our aim was to observe the human impacts. Hypothesis Sector 1 : Our first measurement and our second measurement of all the different biotic features will be relatively the same. Sector 2: The Black Periwinkle will be evenly spread out.

Sector 3: There will only be one tertiary consumer and more than one author Sector 4: All the organisms found on the rock platform will have adaptations towards surviving in the ocean. Sector 5: There will be some evidence of human rubbish. Method Sector 1 : At the rock platform we measured the air temperature and the water temperature using a thermometer, the salinity by using a TTS probe, the wind speed and direction using a anemometer, the relative humidity by using a wet/dry hermetic, light intensity using a light meter and finally the water pH by using universal indicator strips.

We measured all the factors two times and then got an average. Sector 2: To find the abundance of the Black Periwinkle we did a Quadrate study. We all got split into groups and then threw a hula hoop into a random sample area. We then counted the number of Periwinkles in the area of the circle (close to 1 mm). Later we all shared our results and worked out roughly how many organisms there were [average density x area of RPR (mm)]. To find the distribution/abundance we seed a belt transect.

We used a rope that was mm long and then got split into 15 groups and each group then got a meter each, and had to count how many Periwinkles there were CACM each side. We then all got our answers and shared them from O meters to 15 meters. Sector 3: Everyone looked around trying to spot as many different organisms as possible and trying to see what they ate, we then all recorded our results using pen and paper. Sector 4: We all got into a group and wrote down all the different adaptations the teachers said the organisms had. The here main adaptations were structural Physiological and Behavioral.
