Food Web of Sungei Buloh Study Guide

Key Concepts

  • Food Web: A system of interconnected food chains that illustrates the feeding relationships within an ecosystem. It shows the flow of energy between different organisms.
  • Trophic Levels: The position an organism occupies in a food web. Examples include producers, primary consumers, secondary consumers, and tertiary consumers.
  • Producers: Organisms that produce their own food, usually through photosynthesis. In many food webs, these are plants or algae.
  • Consumers: Organisms that obtain energy by feeding on other organisms.
  • Primary Consumers (Herbivores): Organisms that feed directly on producers.
  • Secondary Consumers (Carnivores/Omnivores): Organisms that feed on primary consumers.
  • Tertiary Consumers (Carnivores): Organisms that feed on secondary consumers.
  • Predator-Prey Relationship: An interaction where one organism (the predator) hunts and kills another organism (the prey) for food.
  • Energy Flow: The transfer of energy from one trophic level to the next in a food web. Energy is typically lost at each transfer.
  • Interdependence: The reliance of different organisms within a food web on each other for survival. Changes in one population can affect other populations.
  • Sungei Buloh Wetland Reserve: A specific ecosystem in Singapore, likely containing a unique food web with particular species and interactions.
  • Interactive Simulation: A computer-based model that allows users to explore and manipulate variables within a system, such as a food web, to understand its dynamics.

Quiz

  1. What is the main purpose of a food web? Explain in your own words how it differs from a food chain.
  2. Define the term "trophic level" and provide two examples of different trophic levels within a food web.
  3. Describe the role of producers in an ecosystem and how they form the base of a food web.
  4. What is the difference between a primary consumer and a secondary consumer? Give an example of each.
  5. Explain the concept of a predator-prey relationship and its significance in maintaining balance within a food web.
  6. What happens to energy as it flows from one trophic level to the next in a food web? Why is this important?
  7. Why is the concept of interdependence important when studying food webs? Provide an example.
  8. Based on the source titles, what type of ecosystem is the "Food Web of Sungei Buloh" likely representing? What might be unique about this environment?
  9. What is the benefit of using an interactive simulation to study a food web, as suggested by the second source?
  10. According to the second source, what was one inaccuracy initially present in the "Food Web of Sungei Buloh" model, and how was it addressed?

Quiz Answer Key

  1. A food web illustrates the interconnected feeding relationships in an ecosystem, showing how energy flows between various organisms. Unlike a simple food chain, which depicts a linear sequence of who eats whom, a food web shows multiple interconnected pathways of energy transfer.
  2. A trophic level is the position an organism occupies in a food web based on its feeding habits. Examples include producers (like plants) at the first trophic level and primary consumers (herbivores that eat plants) at the second trophic level.
  3. Producers, typically plants or algae, create their own food through photosynthesis, converting sunlight into energy. They are the base of the food web because all other organisms directly or indirectly depend on them for energy.
  4. A primary consumer is an organism that feeds directly on producers (e.g., a rabbit eating grass). A secondary consumer is an organism that feeds on primary consumers (e.g., a snake eating a rabbit).
  5. A predator-prey relationship is where one organism (the predator) hunts and consumes another organism (the prey). This interaction is crucial for regulating population sizes within a food web, preventing any single species from becoming overly dominant.
  6. As energy flows from one trophic level to the next, a significant portion is lost as heat due to metabolic processes. This limits the number of trophic levels in a food web because there is not enough energy to support a large number of top-level consumers.
  7. Interdependence highlights how different organisms in a food web rely on each other for survival. If one population declines or disappears, it can have cascading effects on other populations that depend on it for food or are preyed upon by it.
  8. Based on the title "Food Web of Sungei Buloh," it likely represents a wetland ecosystem. Wetland environments often have unique characteristics like brackish water, specific plant life (mangroves, etc.), and associated animal species adapted to these conditions.
  9. An interactive simulation allows users to visualize the complex relationships within a food web and to explore the potential consequences of changes, such as the removal or introduction of a species. This hands-on approach can lead to a deeper understanding of the system's dynamics.
  10. The initial working document had an inaccuracy where it was believed spiders were not eaten by birds. This was corrected based on observation, with the updated model showing spiders being eaten by fish instead (suggesting a different predator-prey relationship was identified).
