d) Temperate deciduous forests
Answers
Answer:
a) Tropical Evergreen forests
i) These evergreen forests are found in warm and wet regions.
ii) These are found where the rainfall is more than 200cm, with a short dry season.
iii) These are found in the rainy slopes of western ghats,plains of West Bengal and Odisha and the North-eastern India.
iv) Trees grow very vigorously,reaching a height of about 60cm and above.
v) Some of the commercially useful trees if these FOREST are ebony, mahagony and rosewood.
b) Tropical deciduous forests
They are also called the monsoon forest.
• They Spread over the region receiving rainfall between 200 cm and 70 cm.
• Trees of this forest-type shed their leaves for about 6 to 8 weeks in dry summer.
• These are the most widespread forest of India.
• The common animals found are Lion, Tiger, Pig, Deer and Elephant.
A huge variety of birds, lizards, Snakes and tortoises are also found here.
c) Temperate Evergreen forests
The world's largest temperate rain forests are found on the Pacific coast of North America. The forests start in Alaska and run along the coast to Oregon and California. Isolated patches of temperate rain forests are found in coastal Chile, Norway, the United Kingdom, Japan, Australia and New Zealand. The temperate rain-forest biome, or sets of related ecosystems, support many species of flora and fauna..
CLIMATE
The defining special feature of the temperate rain forest is its climate. The mild weather conditions are maintained by moisture-laden air blown in off the Pacific Ocean...
TALL TREE
One of the most conspicuous special features of the temperate rain forests are the tall evergreen trees dominating the landscape.nd hemmed in by the coastal mountains.
PLANTS
Epiphytes constitute one of the most notable features of the temperate rain forest's flora. Epiphytes are mostly species of mosses and ferns that live on the branches and trunks of trees, especially the broad-leafed maples.
ANIMALS
Wild salmon are one of the most distinctive members of the temperate rain forest's fauna. Six species inhabit the rain forest ecosystem: Chinook, sockeye, coho, pink, steelhead and chum. etc
d) Temperate deciduous forests
Deciduous forests have a long, warm growing season as one of four distinct seasons.
There is abundant moisture.
The soil typically is rich. The leaves dropped from trees provide a steady source of organic material for the soil. Many species live in the soil and break down the organic matter.
Tree leaves are arranged in strata: canopy, understory, shrub, and ground. A great deal of light is therefore filtered out before it reaches the ground.
With the dropping of their leaves during one season, trees stop photosynthesis and enter a dormant period.
Three main types of trees are characteristic of these forests: northern hardwood, central hardwood, and southeast pine and oak.
