International Green Warrior Olympiad Class 9 Sample Paper

Q.1

An individual is trying to reduce their carbon footprint through their diet. Which action would have the most significant impact on reducing carbon emissions?

Q.2

A tropical country experiences frequent severe weather events, including but not limited to drought, hurricanes and cyclones, due to climate change. Its current reliance on large-scale hydropower plants makes it vulnerable to these extreme weather events.
Which of the following clean energy sources is most likely to be resilient to these climate impacts?

Q.3

Consider the following statements and choose the correct option:
Statement 1: Groundwater is primarily recharged through precipitation that infiltrates into the soil.
Statement 2: Groundwater, once depleted, can be quickly replenished through human interventions like pumping water from surface reservoirs.

Q.4

Consider the case study given below and answer the following question:
Case Study: Protecting the Coral Reefs of Raja Ampat, Indonesia
Location: Raja Ampat, a stunning archipelago in Indonesia famed for its thriving coral reefs, biodiversity, and diving tourism.
Challenges:
-Overfishing: Unsustainable fishing practices, including blast fishing and cyanide fishing, have depleted fish stocks and damaged coral reefs.
-Pollution: Plastic pollution, agricultural runoff, and sedimentation from coastal development all threaten the delicate marine ecosystem.
-Climate Change: Rising ocean temperatures and acidification are bleaching and killing coral, the foundation of the reef ecosystem.
Initiatives:
-Marine Protected Areas (MPAs): Establishing and enforcing MPAs restricts harmful fishing practices and allows reefs to recover. Raja Ampat boasts one of the largest MPAs in Southeast Asia, covering over 1.5 million hectares.
-Community-Based Management: Local communities play a crucial role in protecting their reefs. The Coral Triangle Initiative focuses on empowering them through sustainable fishing practices and alternative livelihoods like ecotourism.
-Sustainable Aquaculture: Farming fish responsibly reduces pressure on wild stocks and provides alternative income for fishermen. Locally managed fish farms in Raja Ampat demonstrate successful alternatives to overfishing.
-Coral Restoration: Innovative techniques like coral nurseries and transplantation help regenerate damaged reefs and restore marine biodiversity.
Outcomes:
-Fish stocks are rebounding: The Raja Ampat MPA has shown a significant increase in fish biomass within its boundaries, demonstrating the effectiveness of protected areas.
-Improved water quality: Reduced pollution and sedimentation contribute to healthier corals and a more vibrant marine environment.
-Empowered communities: Local involvement in conservation fosters environmental stewardship and provides sustainable economic opportunities.
Raja Ampat serves as a beacon of hope in marine conservation, demonstrating the effectiveness of community-driven, multi-pronged approaches to protecting life below water. By tackling overfishing, pollution, and climate change, we can safeguard the future of these vital ecosystems and the communities that depend on them
What is a long-term challenge that the case study implies requires continuous global support to ensure the success of marine conservation in Raja Ampat?

Q.5

Consider the case study given below and answer the following question:
Title: Forests as Crucial Carbon Capture Systems
Forests play a critical role in mitigating climate change by capturing and storing carbon dioxide from the atmosphere. Trees absorb carbon dioxide through photosynthesis and use it to grow. The carbon is then stored in the tree's biomass (wood, leaves, branches, and roots) and soil. Forests also help to regulate the climate by releasing water vapour into the atmosphere, which can form clouds and reflect sunlight back into space.
Trees are the most significant carbon sink in forests, storing carbon in their biomass. The amount of carbon stored in a tree depends on its species, size, and age. Young forests capture carbon rapidly due to the quick growth of trees. Middle-aged forests store relatively greater amounts of carbon as trees grow slower but sequester more carbon. Old-growth forests contain large trees that retain carbon for extended periods, albeit at a slower rate due to fewer trees overall.
Forest soils contain diverse forms of carbon influenced by soil type, vegetation, and geography. Soil properties, such as high organic content or frozen conditions, significantly impact carbon storage potential.
The carbon captured by forests is eventually returned to the atmosphere through processes like decomposition and respiration. Different forest types exhibit varying rates of carbon capture and release. Tropical forests capture carbon rapidly but can release it quickly too. In contrast, temperate forests offer a balanced solution.
Effective management strategies, such as forest preservation, sustainable forestry practices, forest expansion, and invasive species control, are crucial in optimising carbon sequestration potential while maintaining ecosystem balance.
Imagine conducting an experiment measuring carbon sequestration rates in four different forest types over the span of a year. Based on your understanding of the case study, which forest type would you expect to demonstrate the highest rate of carbon capture per unit area within a year?

Q.6

Maya, a young activist, is organising a campaign to reduce single-use plastics in her school. She argues that plastic production not only generates plastic waste but also contributes to climate change through:
A. Increasing deforestation for raw material extraction.
B. Methane emissions from decomposing plastic in landfills.
C. Increased reliance on fossil fuels for plastic manufacturing.

Q.7

You are a technician working at a nuclear power plant. You are tasked with performing routine inspections of the plant's various components. To ensure your understanding, your supervisor provides you with a diagram of the plant layout and asks you to identify the labelled components.
Based on the diagram below, identify the main components of a nuclear power plant.

Q.8

You're a wildlife conservationist working in the Himalayas, where a dwindling snow leopard population faces new challenges. Human encroachment has forced wolves into higher altitudes, overlapping with the leopards' territory, while climate change is shrinking their habitat due to melting glaciers.
You propose a conservation plan to address these challenges. Which of the following options is/are the effective and sustainable long-term solution(s), considering ecological balance and ethical implications?
1. Prioritise eliminating the wolf threat to restore the leopards' competitive advantage.
2. Lobby for stricter regulations on human activities near snow leopard habitat.
3. Invest in renewable energy sources to combat climate change.
4. Develop captive breeding programs to supplement dwindling wild populations.

Q.9

A group of students studying ecology in a temperate forest notices a sharp decline in the local frog population. They discover that a new housing development has encroached upon a wetland area that was once home to a diverse array of amphibians.
What is the likely consequence of the wetland habitat loss on the surrounding forest ecosystem?

Q.10

Blair, an environmentally conscious consumer, is shopping for groceries at a local store. She notices a food product with an eco-label that states "Organic" on the packaging. Curious about its meaning, she checks the information available to understand the significance of the label.
In the context of eco-labelling, what does the presence of an "Organic" label on a food product signify based on Emily's observation?
