Q.1 |
Jason is an environmental enthusiast concerned about the sustainability of fish and seafood due to overfishing and its impact on marine ecosystems. He's looking for alternative protein sources to reduce his reliance on fish and seafood in his diet. |

Q.2 |
A community is experiencing increased forest fires due to prolonged droughts caused by climate change. As a disaster management expert, which of the following strategies would you recommend to reduce the impact of forest fires on the community? |

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 |
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.5 |
A group of conservationists is conducting a study in a coastal region known for its diverse ecosystem. They notice a significant decline in the population of native plant species due to the introduction of non-native plants by human activities. As they delve deeper into their research, they aim to assess the significance of native species within this ecosystem. |

Q.6 |
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.7 |
In a discussion regarding the significance of tropical rainforests in global climate regulation, a group of environmental researchers is examining the mechanisms by which these forests contribute to this role. |
|||
Q.8 |
You are watching a wildlife documentary where a pod of migrating humpback whales suddenly changed their course, avoiding a polluted area in the river. It was later shown that the scientists discovered high levels of mercury in the water. |
|||
Q.9 |
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.10 |
A study conducted in the North Atlantic found that a specific population of cod had been overfished for decades. As a result, the average size of cod in the population had decreased by 20%. What are the potential consequences of this decrease in size for the cod population? |
