The metals having density more than 5 are usually known as heavy metals. Density of some heavy metals is as below: Zinc (Zn) 7.13 Iron (Fe) 7.87 Copper (Cu) 8.96 Silver (Ag) 10.49 Lead (Pb) 11.36 Mercury (Hg) 13.55 We use fertilizers which contain elements having density more 5 or more than 5 like zinc sulphate or copper sulphate ets. so we can say that plants take these heavy metals in shape of fertilizers.

How do discarded batteries affect humans and the environment?
In landfills, heavy metals have the potential and the ability to slowly leach into the soil, groundwater or surface water. Dry cell batteries contribute about 88 percent of the total mercury and 50 percent of the cadmium in the municipal solid waste stream. When burned, some heavy metals such as mercury may vaporize and escape into the air, and cadmium and lead may end up in the ash.
What is accumulation of pollutants at successive levels of the food chain.?
The accumulation of pollutants at successive levels of the food chain is known as biomagnification. This process occurs when toxic substances, such as heavy metals or pesticides, are taken up by organisms and become increasingly concentrated as they move up the food chain. Predators at higher trophic levels ingest multiple prey, leading to higher concentrations of these pollutants in their bodies. As a result, top predators can experience significant health risks and ecological impacts due to this accumulation.
Which property measures the space taken up by an object?
The space taken up by an object is called volume.
What can the vast majority of elements in the periodic table be classified as?
The vast majority of elements in the periodic table can be classified as metals. Metals make up the s-block, d-block, and f-block of the periodic table. There are even a few elements in the p-block with metallic properties called metalloids.
Is a metal an element?
Metals are a class of elements. A pure metal is an element. Some metals are alloys, which mean they have more than one metal or element in them. The metal bronze is made of two elements, the metal tin and the metal copper.
What is hyper- accumulation of heavy metals?
Hyperaccumulation of heavy metals is the uptake of heavy metals by plants passed a certain threshold of normal uptake. There are 6 main hypotheses for this phenomena, but the most researched one is the defense-hypothesis which states that the hyperaccumulation helps plants to protect themselves from herbivore/pathogen damage.
Why are electromagnets used for picking up heavy metals?
Well electromagnets have great power so it is understandable that someone would use it to pick up heavy metals.
What are the two heavy metals that make up the core?
The two heavy metals that make up Earth's core are iron and nickel. They are believed to be primarily responsible for the Earth's magnetic field.
What plant is attracted to metal?
Some plants, like sunflowers, have been found to accumulate heavy metals such as lead, arsenic, and uranium in their tissues. This phenomenon is known as phytoremediation, where plants are used to clean up contaminated soil or water by absorbing and concentrating the pollutants.
Why is the volume of metallurgy taken up by two different metals?
Please clarify.
What is the first planet that is made up of heavy metals in your solar system called?
The first planet in our solar system that is primarily made up of heavy metals is Mercury. It has a large metallic core, predominantly made of iron and nickel, which is thought to make up about 60% of its mass.
Why is silver heavy?
Certain groups of people try to classify silver as a heavy metal such as cadmium and mercury, in order to promote fear mongering regarding the use of silver in medicine. The term "heavy metals" is both meaningless and misleading. Just about anything can be toxic if used abusively. In truth, silver, gold, copper and platinum are noble metals, not "heavy metals" like mercury, plutonium or lead. If you look it up in the Wikipedia encyclopedia, it is not found in the list of heavy metals.
How does phytoremediation harvest heavy metals and nitrates from soil and water?
Phytoremediation harnesses the natural abilities of plants to absorb, accumulate, and detoxify heavy metals and nitrates from soil and water. Certain plants, known as hyperaccumulators, can take up these contaminants through their roots and store them in their stems and leaves, effectively reducing their concentration in the environment. Additionally, some plants can transform nitrates into less harmful compounds through biological processes. This eco-friendly technique not only cleans contaminated sites but also promotes soil health and biodiversity.
Which chemical is taken up by the plants and comes out through the leaves of the plant?
Water (H2O) is taken by the roots of plants and it comes out through the leaves during transpiration.
What health problems may arise from this metal water pollution?
Heavy metals tend to accumulate in our body tissues, building toxicity over time.In our case, heavy metals in fresh water get absorbed by tiny organisms that in turn get consumed by larger ones up to fish, which we then catch and eat. The effects are not immediate, but since heavy metals don't tend to be removed from our bodies, they build up. The more contaminated foods we eat, the more the metals build up until they reach toxic levels.
What are used in electric motors and other things to lift up heavy metals and steel objects?
Water
How is fertilizer used by plants?
== == it is taken up either by the roots or leaves
