Question

Formation of tropical forests needs mean annual temperature and mean annual precipitation as

• A. 18-25^o C and 150-400cm
• B. 5-15^oC and 50-100cm
• C. 30-50^oC and 100-150cm
• D. 5-15^o C and 100-200cm

Answer 1

The correct option is A 18-25^o C and 150-400cm

The entire ecosystem is made up of biotic and abiotic factors. Temperature, rainfall, snowfall, constitute some important abiotic factors. As we move from the equator to poles, the temperature range goes on decreasing and rainfall varies from place to place. At the poles, there is hardly any rainfall but snowfall is seen very regularly. Fir tropical rainforests to grow, the temperature in the range of 18-25 degree Celcius is required. Rainfall of around 150-400 cm is also required for the same.

So, option A is the correct answer.
