Statement 3 is correct, as Abies spectabilis is commonly found in the Himalayan region at mid to high altitudes. About Fir Trees (Abies spectabilis): What it is:A slow-growing evergreen conifer commonly found in mountainous regions. Features: Needle-like leaves and conical shape. Adapted to colder climates with moderate moisture. Retains foliage year-round, contributing to high water-use efficiency. Found in: Mid to high altitudes of the Himalayas (2,500–3,700 meters). Prefers cooler and less moisture-stressed environments. Incorrect Solution: a) Statement 1 is incorrect as fir trees grow in mid to high altitudes, typically between 2,500–3,700 meters in the Himalayas, not in low-altitude tropical regions. Statement 2 is incorrect because fir trees are evergreen, retaining their foliage year-round, rather than shedding leaves annually.

• Question 10 of 10 10. Question 1 points Consider the following statements about the Arctic tundra ecosystem: The growing season is extremely short, lasting only a few weeks annually. It supports species such as polar bears, Arctic foxes, and caribou. Permafrost in the tundra is a significant source of carbon emissions. The tundra vegetation is highly resistant to climate change impacts. Which of the above statements are correct? a) 1 and 2 only b) 1, 2, and 3 only c) 1, 2, and 4 only d) 1, 3, and 4 only Correct Solution: b) The fourth statement is incorrect because tundra vegetation is highly vulnerable to climate change. Rising temperatures lead to permafrost thawing, impacting ecosystems. The other statements are accurate as they reflect the tundra’s ecological and climatic characteristics. Incorrect Solution: b) The fourth statement is incorrect because tundra vegetation is highly vulnerable to climate change. Rising temperatures lead to permafrost thawing, impacting ecosystems. The other statements are accurate as they reflect the tundra’s ecological and climatic characteristics.
