Consider the following ecosystems

1. Taiga
2. Tropical Evergreen
3.Tropical Deciduous
4. Tundra

The correct sequence in decreasing order of the albedo values of these ecosystems is
a) 1, 4, 3 and 2
b) 4, 1, 2 and 3
c) 4, 1, 3 and 2
d) 1, 4, 2 and 3

Ans-c

Explanation-As tundra ecosystem comprise of mainly snow , albedo of it is highest. Albedo of taiga is lower than tundra as it is sub arctic climate and has dense forest, trees grow close together. Their dark color makes theiralbedo low and they absorb solar energy readily, keeping them a bit warmer.

Albedo increases when vegetation with its higher albedo begins to cover soil surface. Thus deciduous has more albedo.

Albedo declines due to increase canopy complexity.
