A brush fire started from a nearby village and wiped out 90% of the grasses in the ecosystem shown in the diagram. What may be some effects observed within this ecosystem as a result of the brush fire?
Gases and particles from burning organic matter and biomass may pollute the air. This may affect the air quality permanently or temporarily.
There will be an increase in the infiltration capacity of soil precipitation leading to increased soil erosion.
Reduced organic matter content in the upper layers of the soil as the recycling process of organic matter is interrupted by the destruction of biomass.
Nearby water bodies will be polluted by the eroded sous and polluted air.
Water cycle is interrupted as both the soil and vegation are destroyed. Thus, they temporarily cannot contribute to the cycle.
Reduced carbon fixation.
Reduction in fauna as most are either destroyed or migrate.
During regrowth, the vegation composition may be altered if new species of plants are introduced in the ecosystem.
Reduced growth rate for plants as the organic matter and humus content of the soil is affected negative, hence lower fertility.
