Q.1 |
Given below is a flowchart illustrating how human activities contribute to climate change and its consequences. Identify the gaps marked as A, B, C, and D based on your understanding. |

Q.2 |
The following table shows the average temperature and precipitation for three different biomes. Based on your understanding, answer the following questions.

Q.3 |
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.4 |
Imagine you're a conservation biologist studying the environmental impact of electronics. You're particularly concerned with the extraction of raw materials needed for manufacturing, like lithium and cobalt. |
|||
Q.5 |
Over-extraction of groundwater can lead to various negative consequences. Which of the following is NOT a potential consequence of excessive groundwater extraction? |
|||
Q.6 |
Consider the case study given below and answer the following question: |
|||
Q.7 |
During a summer heatwave, a meteorological study compares temperature variations between an urban area and its nearby rural surroundings. The findings are provided in the graph below. |
|||
Q.8 |
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.9 |
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.10 |
A community relies on a rainwater harvesting system for its water supply. The system collects rainwater from rooftops and stores it in large underground tanks. After a heavy rainfall, the residents notice that the stored water has a brownish colour and an unpleasant odour. |
