Q.1 |
A coastal area witnesses a significant decrease in the population of shellfish due to water contamination. Analysis reveals the presence of persistent organic pollutants (POPs). POPs are resistant to environmental degradation through chemical, biological, and photolytic processes. For this reason, they persist in the environment for a long time. |

Q.2 |
A bustling city faces challenges with its growing wastewater volume and outdated treatment facilities. This untreated wastewater is discharged into a nearby river, leading to algal blooms, low oxygen levels, and fish die-offs. |

Q.3 |
Consider the case study given below and answer the following question: 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.
A farmer is contemplating converting a section of their farmland into a forest to optimise carbon sequestration potential. Which set of actions would best help the farmer achieve this goal? 1. Plant a mix of tree species known for fast growth and high carbon storage capacity. 2. Plant trees that are native to the region. 3. Leave the soil unplanted and unattended to encourage natural regeneration of native vegetation. |

Q.4 |
You typically wash a full load of laundry with hot water (40°C). Based on the provided information, which of the following options would have the potential to reduce your total laundry energy consumption? |
|||
Q.5 |
John is considering installing a heating and cooling system in his new home. He wants an energy-efficient and environmentally friendly option. After researching various systems, he learned about geothermal heat pumps. Which of the following statements is true about geothermal heat pumps? |
|||
Q.6 |
You're the sustainability coordinator for your school, tasked with analysing and improving waste management practices. To assess current methods, you gather information on various practices used by students and staff. |
|||
Q.7 |
An environmental organisation has embarked on a project aimed at restoring a degraded river ecosystem. The project involves reintroducing native fish species that have declined due to habitat degradation and water quality issues. Additionally, efforts are being made to improve overall water quality by implementing measures to reduce pollution and restore natural habitat. |
|||
Q.8 |
You are part of a community initiative aiming to reduce carbon emissions and combat climate change. The group is discussing strategies, and one member proposes focusing on energy efficiency. Which statement best supports the role of energy efficiency in this context? |
|||
Q.9 |
Researchers conducted an experiment to assess the effectiveness of green roofs in reducing indoor temperatures. They compared the energy consumption of buildings with and without green roofs during summer months. The results showed a noticeable decrease in energy usage in buildings with green roofs. |
|||
Q.10 |
You are part of a student-led environmental club focused on sustainability within the local community. As part of a research project, your team collected data on food waste percentages at different stages of the local food supply chain. |
