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

Q.1

During an Earth Science field trip, students are exploring the impact of rising temperatures on the local ecosystem. The students notice a decline in the population of a particular plant species in the area compared to previous years.
Which factor related to climate change is most likely influencing this decline?

Q.2

You're advising a friend on reducing their ecological footprint through dietary changes. Which practical suggestion aligns best with this goal?

Q.3

During a marine conservation seminar, a panel discusses the diverse range of threats posed by ocean plastics to marine life. They emphasise the severe consequences and challenges faced by various species due to plastic pollution in oceans.

Which scenario best illustrates the impact of discarded plastic on marine life?

Q.4

Your city throws away tons of food, leading to environmental issues and wasted resources. Two groups proposed solutions:

Group A:
"Community Kitchens": Establish kitchens that collect discarded food, prepare nutritious meals, and serve them to those facing hunger.
"Urban Composting Network": Create a network of community composting bins and educational programs to turn food scraps into nutrient-rich soil for urban gardens.

Group B:
"Smart Fridges":
Implement high-tech fridges that monitor food freshness and notify owners to prevent expired waste.
"Automated Recycling Plants": Build specialised plants that efficiently process organic waste into fertilisers and renewable energy.
Which group's approach do you think will more effectively reduce food waste and address related challenges? Why?

Q.5

A family went on a camping trip and drank water from an untreated stream. Several days later, they all became ill with vomiting and diarrhoea. Which of the following is the most likely cause of their illness?

1. Contaminated water from the stream
2. Ingestion of a parasite present in the stream water
3. A contagious respiratory illness

Q.6

Which of the following statements describes the role of zoos in endangered species conservation?

1. Zoos primarily exist for entertainment purposes and have no impact on conservation efforts.
2. Zoos serve as a means to display animals but have little involvement in conservation initiatives.
3. Zoos play a significant role in conservation by housing and breeding endangered species.
4. Zoos contribute to the endangerment of species by removing them from their natural habitats.

Q.7

In a study comparing two diverse regions, a Coastal City and a Desert Region, several factors influencing annual rainfall were analysed and recorded in the table below.
Based on this information, which of the following statements is most accurate?

Q.8

The local government introduced a campaign encouraging citizens to repair broken household items rather than replacing them. How does this campaign support responsible consumption and production?

1. Extending the lifespan of products through repair and reuse
2. Promoting continuous purchasing of new products
3. Encouraging constant disposal of items

Q.9

Robert, an environmentally conscious individual, has recently initiated a practice of composting her food scraps and yard trimmings. He intends to utilise the resultant compost as soil enrichment for her garden beds, aiming to reduce dependency on commercial fertilisers and promote sustainable gardening practices.
Considering Robert's endeavour to compost his organic waste and repurpose it for his garden, which sustainable practice does his action primarily demonstrate?

Q.10

In your research on marine ecosystems, you've found evidence suggesting shifts in the distribution of certain fish species. Fish that were once abundant in cooler waters are now migrating to different regions.
