    1. Lion-tailed Macaque: This species is primarily diurnal, meaning it is active during the day and rests at night. They are known for their distinctive mane and tail tuft, and they inhabit the rainforests of the Western Ghats in India.
    2. Malabar Civet: The Malabar Civet is generally nocturnal. It is most active during the night and is rarely seen during the day. It is a critically endangered species native to the Western Ghats and nearby regions.
    3. Sambar Deer: The Sambar Deer is largely nocturnal or crepuscular (active during twilight). It tends to be most active during the early morning and late evening but can also be seen foraging at night.

    Given this information, two of the listed fauna (Malabar Civet and Sambar Deer) are generally nocturnal or most active after sunset. Therefore, the correct answer is: Only two.

    Let's analyze the statements: Statement-I: Marsupials are not naturally found in India. This statement is correct.

    Let’s analyze the statements:

    Statement-I: Marsupials are not naturally found in India. This statement is correct. Marsupials, such as kangaroos and koalas, are primarily found in Australia and nearby islands. They are not native to India.

    Statement-II: Marsupials can thrive only in montane grasslands with no predators. This statement is incorrect. Marsupials inhabit a wide variety of environments, including forests, grasslands, and deserts. They are not limited to montane grasslands and can coexist with predators, as evidenced by their presence in diverse habitats in Australia, where they have adapted to various ecological niches.

    Therefore, the correct answer is: Statement-I is correct but Statement-II is incorrect.

    Climate change significantly impacts biodiversity by altering ecosystems, species distributions, and the survival of both plant and animal life. Key ways climate change affects biodiversity include:

    1. Habitat Loss and Fragmentation: Rising temperatures and changing precipitation patterns can alter or destroy natural habitats. For example, polar ice caps melting reduce habitats for species like polar bears, while coastal habitats are eroded by rising sea levels, affecting marine and bird species.
    2. Changes in Species Distribution: As temperatures rise, many species are forced to migrate to cooler regions, either toward the poles or to higher altitudes. Species unable to move or adapt quickly face extinction. For instance, mountain species may lose habitable areas as the climate warms.
    3. Disruption of Ecosystem Services: Ecosystems provide essential services such as pollination, water purification, and carbon storage. Climate change disrupts these services. For example, changing weather patterns can impact the flowering times of plants, which in turn affects pollinators like bees.
    4. Altered Food Chains: Temperature shifts can affect species’ life cycles, leading to mismatches in food availability. If prey or plant species decline or change their reproductive timing, predator species may struggle to find food.
    5. Increased Extinction Risk: Species that cannot adapt to rapid changes in climate, such as amphibians, corals, and some plants, face a higher risk of extinction. The International Union for Conservation of Nature (IUCN) predicts that climate change could contribute to the extinction of up to one million species in the coming decades.
    6. Ocean Acidification and Coral Bleaching: As oceans absorb more CO₂, they become more acidic, affecting marine biodiversity. Coral reefs, home to about 25% of marine species, are highly vulnerable to bleaching caused by warmer waters and acidification, leading to declines in marine biodiversity.
    7. Increased Invasive Species and Disease Spread: Warmer climates enable invasive species and pests to expand into new areas, often outcompeting native species. In addition, the spread of diseases, such as those affecting amphibians and marine organisms, is facilitated by changing environmental conditions.
    8. Impact on Migration Patterns: Many species, particularly birds and marine animals, rely on stable climatic conditions to time their migration. Disruptions caused by unpredictable weather patterns can lead to reproductive failure or death.

    Overall, climate change poses a major threat to global biodiversity, with far-reaching consequences for ecosystems, species survival, and human well-being.

    Ocean pollution is primarily caused by plastics, chemical waste, agricultural runoff, oil spills, and sewage discharge.

    Ocean pollution is primarily caused by plastics, chemical waste, agricultural runoff, oil spills, and sewage discharge. Plastics, which make up around 80% of marine debris, pose severe threats to marine life as they can be ingested or cause entanglement, leading to injury or death. Chemicals from pesticides and fertilizers lead to nutrient pollution, creating dead zones where marine life cannot survive. Oil spills suffocate marine animals and destroy habitats like coral reefs. For humans, consuming seafood contaminated with microplastics and toxins leads to health issues like hormonal imbalances, neurological disorders, and cancers. Ocean pollution also undermines economies dependent on tourism and fishing, making it a pressing environmental concern.

    Deforestation significantly impacts biodiversity by destroying habitats that are critical for various species. When forests are cleared, many plants, animals, insects, and microorganisms lose their homes, leading to a decline in species richness. This loss of biodiversity disrupts ecosystems and weakens their resilience, making them more vulnerable to disturbances like climate change, diseases, and natural disasters. Deforestation also contributes to soil erosion, reduces the land’s ability to store carbon, and increases greenhouse gas emissions, exacerbating global warming. The broader environmental consequences include altered rainfall patterns, decreased soil fertility, and a loss of ecosystem services like water filtration and air purification, which are vital for human survival.
