Q.1 Q.2 Q.3 Q.4 Q.5 Q.6 Q.7 Q.8 Q.9 Q.10

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.
Which method is most effective in reducing POPs in aquatic environments?

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A bustling city faces challenges with its growing wastewater volume and outdated treatment facilities.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.
Complete the flowchart by accurately identifying the specific methods and techniques A, B and C utilised in primary, secondary, and tertiary wastewater treatment aimed at enhancing the quality of discharged water.

Q.3

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.

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?

A. Washing smaller loads more frequently instead of a full load once a week.
B. Switching to warm water (30°C) for most washes.
C. Air-drying your clothes instead of using the dryer entirely.
D. Cleaning the lint screen in your dryer after every load to improve airflow.

Q.5

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.

What does this experiment suggest about the role of green roofs in climate change mitigation?
