What abiotic factors are affected by deforestation?

Soil Impact

The soil that provides nutrients for vegetation in ecosystems is also affected by deforestation. Soil in deforested areas is exposed to more sunlight, which increases the soil temperature and oxidizes the carbon in the soil to carbon dioxide.

How does deforestation affect energy flow?

But trees also release water vapour into the atmosphere, which turns into rain and feeds hydroelectric power stations, and this new research suggests that wider deforestation can reduce overall rainfall and therefore energy production.

How does energy flow in an ecosystem?

Trophic Levels. Energy flows through an ecosystem in only one direction. Energy is passed from organisms at one trophic level or energy level to organisms in the next trophic level. … Producers are always the first trophic level, herbivores the second, the carnivores that eat herbivores the third, and so on.
