Explain the impacts of toxic metals in soils on plant growth and vegetation patterns.

The various impacts of toxic metals in soils on plant growth and vegetation patterns are:

The impact of the toxic metals are harmful for the soil and plants and the heavy metals are present in the environment but they are less in the concentration and iron, copper and nickel are necessary for the plants growth but in the very little amount and the lead metal are very harmful for the plants. The higher presence of the metal decreased the concentration of the other metals and it is very important for the growth of the plants. The presence of the higher concentration of the heavy metals in the soil caused the damage of the cells.

The presence of metals alter the soil ph. Generally high concentration zinc, cadmimun decreases the soil ph and affect the plant growth.

Excess presence of any metal can decrease the concentration of other metal, which can be very important for the growth of a particular that plant.

High concentration of the heavy metals in the soils causes the cells to damage. While high concentration of some metal ions disturb the homoestasis of plants.
