Albedo is a measure of the reflectivity of a surface. The higher the albedo value, the more it reflects light, and the lower the value, the more it absorbs light.

Option 1 suggests that Taiga has the highest albedo followed by Tundra, Tropical deciduous, and Tropical evergreen. This order is not correct as Taiga does not have the highest albedo among the given ecosystems.

Option 2 suggests that Tundra has the highest albedo followed by Taiga, Tropical evergreen, and Tropical deciduous. This sequence is also not correct as the albedo of tropical evergreen is usually lower than that of tropical deciduous.

Option 3 suggests that Tundra has the highest albedo followed by Taiga, Tropical deciduous, and Tropical evergreen. This sequence is correct. Tundra typically has a high albedo because its surface is often covered by ice or snow which reflect much of the sunlight. Taiga, being boreal forests, has lower albedo as the trees absorb more sunlight. Tropical deciduous and Tropical evergreen have even lower albedos due to dense vegetation.

Option 4 suggests that Taiga has the highest albedo followed by Tundra, Tropical evergreen, and Tropical deciduous, which is
