The correct answer is option 2 - Coniferous forests. Taiga is a type of forest ecosystem characterized by coniferous trees, such as pine, spruce, and fir. These forests are usually found in high latitudes, particularly in the northern parts of North America, Europe, and Asia. Taiga forests have cold climates and long winters, with short and cool summers. The trees in the taiga are adapted to the harsh conditions, with needle-like leaves that help them conserve water and withstand the cold temperatures. The taiga is also known as the boreal forest or the snow forest, and it plays a crucial role in global climate regulation and biodiversity conservation. It is an important habitat for animals like bears, wolves, lynx, and many bird species.
