Which of the following type of ecosystem is expected in an area where evaporation exceeds precipitation, and mean annual rainfall is below 100mm:

Options

A. Grassland
B. Shrubby forest
C. Desert
D. mangrove

Answer

c

Explanation

In true desert biome rainfall is less than 100mm/year, characterised by extremely hot days end cold nights. Evaporation from true desert alwaays exceeds 7-50 times the precupltation (rainfall). Desert ecosystem of biomes are more in Northerm hemisphere than Southern hemisphere.
Whereas Grassland ecosystem receives medium rain fall ranging from 25-75 cm/yr, but evaporation rate is not higher than precipitation rate.
Shrubby forest receives rainfall 90 150 cm/yr.
Mangrove forests receive annual rainfall ranging from 100 150 cm/yr. Thus, there options are wrong.
