Q.1 |
A scientist is monitoring the water quality of a lake used for recreational activities. She observes a sudden increase in the lake's phytoplankton population, followed by a decrease in the DO level and a rise in fish mortality. This phenomenon is most likely due to: |

Q.2 |
Biodiversity loss due to deforestation can have a cascading effect on the ecosystem. Which of the following is the LEAST likely consequence of widespread species extinction? |
|||
Q.3 |
You're passionate about reducing your environmental footprint, particularly concerning packaging materials. You've come across a study that highlights the significance of recycling and reuse in lessening the environmental impact of packaging. |

Q.4 |
A small community in a rural area relies on a well for its drinking water. However, recent tests have shown that the well water is contaminated with bacteria. The community is concerned about the health risks posed by the contaminated water and is considering various options for addressing the problem. |

Q.5 |
In a region prone to erratic weather patterns, farmers face the recurring challenge of water scarcity. A group of agricultural researchers suggests adopting sustainable practices to mitigate the effects of drought. What would be the most effective way to implement this solution? |

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.7 |
You're a municipal waste manager responsible for handling electronic waste (e-waste) in your city. During a routine inspection of the e-waste disposal facility, you notice a significant amount of discarded electronic devices, including computers, monitors, and smartphones. Concerned about potential health hazards, you decide to educate the public about the risks associated with improper disposal of these devices. |

Q.8 |
A scientist is studying the effects of climate change on a tropical rainforest. She measures the amount of water vapour in the atmosphere and finds that it has increased by 10% over the past decade. What does this suggest? |
|||
Q.9 |
A rural village has limited access to electricity, relying primarily on kerosene lamps for lighting. Kerosene use has been linked to respiratory problems and indoor air pollution. The village council is considering ways to improve access to clean and reliable electricity. Which of the following would be the most effective long-term solution to address both health concerns and energy needs? |
