Question

What would you hypothesize about changes in albedo as a result of the loss of mosses and lichen and gain in cyanobacteria?

Answer 1

Terrestrial Lands are colonized by biocrusts that incorporate cyanobacteria, mosses, lichens, and heterotrophs. In numerous drylands, biocrusts are likely the prevailing source of carbon and nitrogen in the atmosphere.

Step-by-step explanation:

• Recent investigations shows that environmental change may affect biocrust network piece by taking out key types of mosses and lichens, which are huge supporters of biogeochemical and hydrological works in drylands.

• This atmosphere initiated loss of mosses and lichens for early successional cyanobacteria-ruled biocrusts additionally lessens the naturally dull, finished soil surface, which thus builds the bounty of lighter, smoother surface spread.

• In this way, a move in biocrust network states could cause the quick change of dryland albedo and energy balance by returning energy to the climate that was once consumed by the dull biocrust surfaces.

Answer 2

As per the new research from journal scientific reports says that a change in climate kills the mosses and lichens in biocrusts.

Step-by-step explanation:

Due to the climatic change the mosses and lichens are killed and the drylands reflects sunlight back to the space.

Soil surface communities such as mosses, lichens, and cynobacteria are found in drylands affects the soil wetting and drying after rainfall events.

From the experiment it is known that the soil moisture and rainfall data shows how biocrusts modify soil water gains and losses after rainfall under temperature(2.5°C warming) and rainfall(33% reduction).

After the rainfall both rainfall and biocrust increases soil water gains and experimental warming , rainfall intensity and soil moisture decreases them.

The dead biocrust release all the atmospheric carbon they stored as they grew.
