Teknik Menjawab Soalan - Describe Eutrophication Process (UPDATED FOR SPM 2017).

*This post was originally posted back in 2013. I realized one of the trial question 2017 asked about eutrophication. So, I'm digging old treasures just for you SPM 2017 sitters.

1. Eutrophication is one of the most famous question for Biology SPM.

Download the rest of the question here.
To answer the question above, I give you technique to answer it by using FADDDDD ( 1 F & 5 'D's).

2. The FADDDDD outline:

3. The specific question for this FADDDDD would be about the process & consequence of eutrophication. Let's discuss what are the initials in the FADDDDD:

F - Fertilizers
A - Algal bloom
D - Die (submerged plants)
D - Die (aquatic life aka fishes)
D - Die (alga itself!)
D - Decomposition
D - Dead zone

4. The FADDDDD is favorable as it covers all important points needed for full marks (terms, explanations/processes, & examples - remember PEE system in my previous posts). Below is the example of a good answer from an A-list student:


Q: Discuss the eutrophication process which leads to a high BOD in an ecosystem. 

Answer Outline:

The answer is given full marks (nearly 100%) because it contains these important points:

1. Can you see the red bold words? Those are the important terms (istilah) enlisted as FADDDDD.
2. Can you see the blue bold words? Those are the right examples.
3. Can you see the red-underlined sentences? Those are the correct explanations.
