You are required to write up a report to present and evaluate the data collected on the excursion to long reef rock platform

Aim:

1) To investigate the types of plants and animals that occur in the tidal wave- shelf ecosystem.

2)         To measure many physical and chemical components.

3)         To measure distribution and abundance of tidal didder-shelf animals.

4)         To investigate adaptations of organisms to the tidal rock-shelf ecosystem.

Introduction:

Long bay located on the gray side of long reef point has a mixture of abiotic factors causes some organisms of the same species to not live with each some other because they be not adapted. Organisms that subsist in tidal rock-shelves are subject to great physical and chemical variations such as, oceanson concentration, temperature, and acidity. Different areas of the tidal rock shelf experience antithetical physical and chemical conditions, which affects the distribution and abundance of tidal rock-shelf organisms.

Apparatus:

Refractometer

Quadrat

Universal indicator

Dichotomous learn folders

Salinity meter

Sample bottles

Hand lens

bucket

Methods:

A) Abiotic factors

1)         To measure the PH value of water, fill the sample bottle approximately 1/3 full with water from the sea and rock-pool. Add five drops of universal indicator solution and equality the colour produced with the colour chart.

2)         To measure and record the temperature at:

I)         A depth of 5cm below the surface in a rock pool at a rock pool at the highest level.

II)         The ocean

III)         Air, however first wipe the thermometer from any water in order to get accurate results.

3)         For salt concentration suck two samples of water from the sea and rock pool. Use the brininess meter to measure the salt content of your water.

B) Distribution and Abundance

1)          plant groups.

2)         Each group determined the abundance of rock shelf animals above the high tide mark by exploitation a quadrat

3)         Determine the abundance at the tidal rock pool using a quadrat.

4)         Determine the abundance at...

The essay is informational, but doesnt give the kind of real scientific info that would be necessary for a more professional piece. trusty try.
