Topic 1Protista -

Ecological Interaction

Organisms interact with each other and the physical environtment. In an essay or oral presentation, explain how the response of diatom populations to a drop in nutrient availability can affect both other organisms and aspect as of the physical environment (such as carbon dioxide concentration).

SUMMARY*Diatom merupakan protista chromalveolata dari

kelompok Stramenopila.

*Diatom merupakan organisme autotrof sehingga digolongkan sebagai fitoplankton yang berfotosintesis mengubah CO2 menjadi O2.

*Diatom memiliki peranan ekologi sebagai produsen primer.

*Menurunnya populasi diatom dapat mempengaruhi rantai makanan organisme perairan.

*Jika populasi diatom menurun maka dapat mengakibatkan terakumulasinya CO2 dalam perairan.

*Terakumulasinya CO2 dapat meningkatkan keasaman perairan dan berdampak pada global warming.
