Which one of the following statements is NOT correct?
- A.Mahogany is a timber species of Tropical Rainforest
- B.Chaparral vegetation is found in Taiga climate
- C.Lichens are predominantly found in Tundra region
- D.Sal is a representative species of Moist Deciduous Forest
Correct answer
Explanation
The correct answer is B. Chaparral is the shrub vegetation of the Mediterranean climate in California, not of the cold Taiga, so this statement is incorrect.
Chaparral is a dense growth of hardy, evergreen, small-leaved shrubs adapted to hot, dry summers and mild, wet winters. The same type of scrub is called maquis around the Mediterranean Sea, mallee in Australia and fynbos in South Africa. The Taiga, by contrast, is the belt of coniferous forest with pine, spruce, fir and larch that stretches across northern Russia, Scandinavia and Canada, where winters are long and very cold.
A is correct because mahogany, like ebony and rosewood, is a hardwood of the hot, wet equatorial forests. C is correct because mosses and lichens, along with small shrubs, are the main plants of the treeless Tundra. D is correct because sal, with teak, is typical of India's moist deciduous forests in areas of 100 to 200 cm rainfall.
Exam tip: Mediterranean scrub names: chaparral (USA), maquis (Europe), mallee (Australia), fynbos (South Africa).
