Q.2	Consider the following statements and choose the correct option: 1. Debris accumulation in oceans primarily consists of organic waste, which enhances marine biodiversity by providing habitats for various species. 2. Sustainable aquaculture involves utilising antibiotics to control diseases and enhance fish growth in farms. 3. Coastal development and shoreline alterations significantly impact marine habitats or disrupt the natural flow of sediments in coastal areas. 4. Overfishing contributes to the creation of dead zones due to the imbalance in marine ecosystems caused by the removal of certain fish species.
	a) Statements 1 and 2 are correct but statements 3 and 4 are incorrect.		b) Statements 1 and 2 are incorrect but statements 3 and 4 are correct.
	c) Statements 2 and 4 are incorrect but statements 1 and 3 are correct.		d) Statements 1 and 3 are incorrect but statements 2 and 4 are correct.

Q.3	A group of students, with a keen interest in studying a wide array of plant and animal species in their natural habitat, is planning an educational expedition. They aim to explore a biome that offers the highest biodiversity for their research. Which biome among the following options would provide the most diverse range of plant and animal species for the students to observe?
	a) Tundra		b) Tropical rainforest
	c) Boreal forest		d) Temperate forest

Q.4	A farmer uses a private well to irrigate his crops. He notices that the well water has become increasingly salty over the past few years, affecting the growth and yield of his crops. What could be the most likely reason for this increase in salinity?
