Answer:
Temperate Deciduous forest biome contains nutrition-rich environment that filters the pollutants.
Step-by-step explanation:
The temperate deciduous forests are filled with trees and often the fallen leaves and other organic matters of the trees forms the nutrients of the soil underneath as the natural decay of these organic matters leads to increase in the soil nutrient content thereby enriching the quality of the soil as a whole.
They also does the ecosystem service of filtering the water from the pollutants. The natural organic matters are one of the best filters and they help in filling the aquifers with fresh non polluted or at least less polluted water.
Example: Bear Grylls’ Discovery channel programme where he would often use leaves for filtering the polluted water.
