Concept:Spruce and cedar are coniferous trees found in temperate coniferous forests at higher altitudes.
Explanation:Spruce and cedar are types of coniferous trees that grow in temperate coniferous forests.
These forests are found between 1500 and 3000 metres above sea level in mountainous regions.
Other common coniferous trees in this zone include pine, deodar, and silver fir.
Temperate coniferous forests are distinct from tropical evergreen forests, which are near the equator and have broadleaf trees like rosewood and mahogany.
They are also different from monsoon forests (tropical deciduous forests), which shed leaves in dry summer and are widespread in India.
Temperate deciduous forests, not listed among options, contain oaks and chestnuts at lower elevations (1000–2000 m).
Thus, spruce and cedar are characteristic of temperate coniferous forests.
