2. Decomposers break down dead organisms or dead matter into simple substances

Primary 6 students should understand the function of producers and decomposers in the ecosystem, as this knowledge will likely be one of the food chain questions to be tested on the PSLE exam. Food producers, such as green plants, make food for consumers, while decomposers break down dead organisms or matter into simple substances.

Knowing the roles of these organisms will enable students to understand how living things depend on each other and the significance of preserving a healthy and balanced ecosystem.

Example:

3. Understanding How the Increase/Decrease of Organisms in a Food Chain/Web Will Impact Other Organisms.

To score full marks in 2-mark questions about Food Chains and Food Webs, students should comprehend the roles played by different organisms in the ecosystem and how changes in one part of the ecosystem can affect other parts. Understanding this demonstrates a deeper comprehension of how living things are interconnected.

Below is an example of applying the understanding above to the question:

Encourage your Primary 6 students to practice regularly and seek help when needed to achieve academic success on the PSLE exam. By using the correct terms to describe food relationships, understanding the importance of producers and decomposers, and comprehending how changes in an ecosystem can impact other organisms, your child will be well-prepared to tackle Food Chain and Food Web questions on the PSLE exam.
