Explanations:Mountain forests are a specific type of forest ecosystem that is found in high-altitude regions. These forests are characterized by their cooler temperatures, high precipitation, and the presence of coniferous trees. The climate in these regions is often harsh, with cold temperatures, heavy snowfall, and strong winds. As a result, the trees that grow in these forests must be adapted to these challenging conditions.
One of the key features of mountain forests is the presence of coniferous trees, which are well-suited to the cold climate. Conifers, such as cedar, have needle-like leaves that reduce water loss and a conical shape that helps to shed snow. These adaptations allow them to survive in the harsh conditions of mountain forests.
Among the options provided, cedar is the tree species that is commonly found in mountain forests. Cedar trees are conifers that are well-adapted to cold climates and high altitudes. They are found in various mountainous regions, including Kashmir, Darjeeling, and Sikkim. Cedar trees are known for their aromatic wood, which is used in construction, furniture making, and as a source of essential oils.
Teak, on the other hand, is a tropical hardwood tree that is found in warm, humid climates. It is not adapted to the cold, high-altitude conditions of mountain forests. Cacti are adapted to arid and desert environments, where they can store water and withstand high temperatures. They are not found in the cooler, wetter mountain forests. Sundari trees are found in the mangrove forests of the Sundarbans, which are located in the coastal regions of West Bengal and Bangladesh. They are not adapted to the high-altitude, cooler climates of mountain forests.
Therefore, the correct answer is cedar, as it is the tree species that is commonly found in mountain forests due to its adaptation to cold climates and high altitudes.
