Q.3

Researchers conducted an experiment to evaluate the impact of controlled burning on grassland ecosystems. The results indicate an increase in plant diversity post-burn.
What is the likely reason for this observation?

Q.4

In a biodiversity conservation project, two strategies were implemented to protect endangered species: Strategy A focused on captive breeding programs, while Strategy B emphasised habitat restoration and protection. Which strategy is more likely to result in the long-term conservation of endangered species?

Q.5

You are an environmental consultant hired by a local community to assess the potential environmental impacts of a proposed aquaculture farm. The farm plans to raise salmon in open-net cages in a bay adjacent to a sensitive coral reef ecosystem.

Based on your knowledge of aquaculture and the local environment, which of the following potential environmental concerns should you prioritise in your assessment?

1. The farm's operations could increase the risk of eutrophication
2. The farm's waste products could pollute the water and harm the coral reef
3. The farm will alleviate pressure on overfished wild populations

Q.6

In urban areas, stormwater runoff often carries pollutants into local water bodies, affecting nearby ecosystems.
Which statement accurately describes the impact of this runoff on aquatic life?

Q.7

You've been tasked with organising a community waste management initiative. While researching the potential hazards of various types of waste, you discover the significant threat posed by e-waste to the environment. Based on this information, what is the primary reason why e-waste poses such a significant threat?

Q.8

A small community in a remote, arid region is facing water scarcity. Their traditional farming practices are no longer sufficient to sustain the community's needs. To ensure long-term food security and water conservation, the community is considering adopting a new farming approach.

Which farming practice would be the most sustainable option for the community to adopt in the long term, considering both water conservation and food production?

Q.9

Consider the case study given below and answer the following question:

Case Study: Rejuvenating the Red Desert

The once fertile plains of the Red Desert now lie barren and parched. Decades of unsustainable agricultural practices, deforestation, and overgrazing have stripped the land of its topsoil, leaving behind a landscape of eroded gullies and windblown sand. The local community, dependent on the land for their livelihood, faces diminishing harvests and increasing dust storms.

The Challenge: Restoring the Red Desert requires a multi-faceted approach that addresses both the physical and social dimensions of land degradation. The key challenges include:

-Soil erosion and nutrient depletion: Restoring soil fertility is crucial for supporting plant growth.
-Water scarcity: The arid climate presents a significant challenge for plant growth. Implementing water harvesting systems like rainwater cisterns and promoting drought-resistant crops can optimise water use.
-Loss of biodiversity: Restoring native plant and animal populations is essential for creating a healthy and resilient ecosystem. This can involve assisted regeneration, seed dispersal, and creating wildlife corridors.
- Community engagement: Sustainable land management requires the active participation of the local community. Building trust, providing training, and ensuring equitable access to resources are crucial for long-term success.

The Outcome: Over time, the Red Desert undergoes a remarkable transformation. Eroded gullies are filled with fertile soil, native plants flourish, and animal populations return. The community experiences increased food security and improved livelihoods, thanks to sustainable farming practices and diversified income sources. The success of the program serves as a model for other communities facing land degradation, demonstrating the power of collaboration and knowledge-based solutions in restoring lost ecosystems and building a sustainable future.

Which of the following statement(s) describes the relationship between deforestation and soil erosion in the Red Desert?

1. Deforestation disrupts the water cycle, reducing rainfall and increasing soil dryness, indirectly leading to erosion.
2. Deforestation directly causes soil erosion by exposing soil to wind and rain.
3. Deforestation increases rainfall, leading to flash floods and soil washout.

Q.10

Consider the case study given below and answer the following question:

Case Study: The Müller Family's Journey to Renewable Energy

The Müller family, residing in a charming village in the German countryside, had always been conscious about their environmental impact. In 2022, they decided to take an active step towards a greener lifestyle by installing a rooftop solar panel system. Their primary motivation was to reduce their reliance on fossil fuels and contribute to mitigating climate change. However, as they embarked on this journey, they discovered a plethora of other benefits:

Environmental Benefits:
-Reduced Carbon Footprint: The solar panels generated clean energy, leading to a significant reduction in their carbon emissions. This translated to a cleaner environment for their family, their community, and the planet.
-Improved Air Quality: By relying less on fossil fuels, the Müllers contributed to cleaner air in their region, which improved their overall health and well-being.

Financial Benefits:
-Reduced Electricity Bills: The solar panels generate enough electricity to cover a significant portion of their household energy needs, resulting in substantial savings on their monthly electricity bills. This provided them with financial stability and freed up resources for other expenses.
-Government Incentives: The German government offers various financial incentives for individuals and families adopting renewable energy solutions. The Müllers took advantage of these incentives, further reducing the cost of their solar panel system and accelerating their return on investment.

Lifestyle Benefits:
-Energy Independence: The Müllers achieved a sense of energy independence by generating their own clean energy. This gave them greater control over their energy consumption and reduced their dependence on the national grid, especially during peak hours.
-Enhanced Home Value: Homes with renewable energy systems are becoming increasingly sought-after, leading to a potential increase in the value of the Müller's property.

Overall Impact:
The Müller family's experience showcases the numerous benefits of adopting renewable energy in a domestic setting. Their commitment to environmental sustainability not only helped them create a cleaner future but also resulted in financial savings and enhanced their quality of life. Their story serves as an inspiration for others to consider switching to renewable energy and contribute to a more sustainable future.

The Müller family experienced a change in their lifestyle that resulted in increased energy consumption. Which of the following strategies could they implement to maintain their energy independence?

A. Install additional solar panels to increase energy generation.
B. Utilise a battery storage system more efficiently.
C. Increase their reliance on the national grid.
D. Install additional solar panels to increase energy generation.
