Question

One of the following is commonly found in temperate coniferous forest is
A. Shorea robusta
B. Pinus wallichiana
C. Dipterocarpus
D. Prosopis
E. Quercus

Answer 1

Coniferous forests are considered as the largest terrestrial biome which has a rich vegetation of cone-bearing needle-leaved or scale-leaved evergreen trees. Northern Eurasian coniferous forests are called taiga or boreal forest. Both of these terms are used for describing the entire circumpolar coniferous forest with its lakes, bogs, and rivers.

Complete step by step answer: Coniferous forests cover mountains in many parts of the globe. Pines, spruces and firs are the dominant trees in it. They're similar in shape and height and infrequently form an almost uniform stand with a layer of low shrubs or herbs beneath. Mosses, liverworts, and lichens cover the forest floor.
Temperate evergreen forests are found predominantly in areas with warm summers and funky winters, and vary enormously in their forms of plants. In some, needle-leaf trees dominate, while others are home primarily to broadleaf evergreen trees or a combination of both tree types.
Temperate evergreen forests are common in regions which experience mild winters and heavy rainfall. Many species that inhabit these forests are pine, cedar, fir, and redwood. These types of forests sustain the best levels of biomass in any terrestrial ecosystem and are notable for trees of massive proportions in temperate rainforest regions.
Generally these forests are simple and consist of two layers: an overstory and understory. However, some forests support a layer of shrubs. Pine forests support an herbaceous ground layer which is dominated by grasses and forbs but the moist conditions found in temperate rainforests favor dominance of ferns among other species. Huge trees dominate certain forest areas which is an unusual ecological phenomena occurring in western North America, southwestern South America.
Thus, the correct answer is b, Pinus wallichiana.

Note: Temperate rain forests occur in 7 regions around the world - the nation-state, the Validivian forests of southwestern South America, the rain forests of latest Zealand and Tasmania, the Northeastern Atlantic, southwestern Japan, and regions of the eastern sea.
