2 Marks for 'Food Chains and Food Web' Questions

As a parent of a Primary 6 student, you undoubtedly want your child to perform well on the upcoming PSLE exam. While the exam is still several months away, Primary 6 students must start preparing now to effectively approach and answer exam questions. In this article, we will guide you through the essential steps to help your child score full marks in 2-mark questions related to Food Chains and Food Webs in Primary 6 Science. Understanding these concepts is critical to comprehending how organisms interact with each other in an ecosystem. With our expert tips and advice, your child will be well-equipped to tackle questions about food webs and chains on the PSLE exam.



The child describes food relationships among organisms

1. Use the Correct Terms to Describe Food Relationships


To understand food relationships and Ecology, it is essential to use the correct terms to describe the various roles of organisms in an ecosystem. By using the correct terms, students can better comprehend the roles of organisms in an ecosystem and how they interact.

  1. Prey, Predator

  2. Herbivore, carnivore, omnivore

  3. Producer, consumer, decomposers

Below is an example of using the terms above in answering the questions:


sample question in food chain and food web

2. Know How to Describe the Importance of Producers and Decomposers in PSLE Science Questions


Know How to Describe the Importance of Producers and Decomposers
  1. Food producers make food for consumers, such as green plants

  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:


Sample question about transfer of energy in an ecosystem

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:


Sample question on the impact of increase and decrease of organism in a food chain

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.
