Question

LS 10 soil pollution and LS 11 bio geo chemical cycles

Answer 1

Soil pollution:-


Soil pollution is defined as the presence of toxic chemicals (pollutants or contaminants) in soil, in high enough concentrations to pose a risk to human health and/or the ecosystem.




Biogeochemical Cycle:-


Altered biogeochemical cycles combined with climate change increase the vulnerability .... greater than natural ones.,, For phosphorus, the effect of added phosphorus on plants

The most well-known and important biogeochemical cycles are shown below:

Carbon cycle.

Nitrogen cycle.

Nutrient cycle.

Oxygen cycle.

Phosphorus cycle.

Sulfur cycle.

Rock cycle.

Water cycle.
