The field study that was created through the Biology excursion to the Homebush Bay mangrove ecosystem presented clear evidence of the interactions and relationships of all factors of the environment, especially the abiotic and biotic features.
All abiotic and biotic features that were expressed within the aim were observed and tested, throughout a series of stations and activities that the students participated in. The results varied from each group, and were also affected by the heavy rainfall that occurred the night prior to the excursion. Salinity, pH levels, temperature, wind speed and turbidity as well as the abundance and distribution of various organisms within the ecosystem was studied intensely.
As expressed through the hypothesis made, human influence has had an enormous impact on the natural features of this environment. As a result of the area being a historical dumping site for many industries and companies, the water has become contaminated, therefore resulting in the marine animals becoming toxic and unsafe. Many strategies have been put in place by the council and public to help manage this issue, such as the storm water canal and the floating pollution boom, used to stop and capture any waste material that does not belong in the water.
Additionally, many of the organisms have adapted to the particular environment in which they are found in. This is as a result of the different beneficial relationships that have been made between species, and the behaviours of such animals and plants to ensure the greatest chance of survival. This is exemplified through the concept on pneumatophores and other plants, as well as the physical adaptations of many animals such as the sacred ibis.
The excursion was extremely insightful and built upon the knowledge of all students of how an ecosystem has many functions and is made up of numerous factors
