A species of buttercup (A) is thought to be able to accumulate nickel in its tissues. A comparable spp. (B) is not an accumulator.
Species A therefore may be useful for removing nickel pollution from the soil.
Each species of buttercup were seeded into two separate plots, one of which had previously been treated with 3g of nickel sulphate per square meter. Watering and other variables were controlled in all the plots
A month after germination, the populations were counted using quadrats of 1m2 and the following results were obtained:
Species A
B
a.
Untreated plot
486 plants in 6 quadrats 584 plants in 8 quadrats
Treated plot
608 plants in 8 quadrats 115 plants in 5 quadrats

An organism which is capable of absorbing nickel is used to decrease the pollution caused by nickel.
Explanation:
- nickel is one of the harmful material that is usually accumulated in the soil. As a result of this it is required that the nickel is removed immediately.
- For this purpose we use an accumulator and measure the amount of nickel which is the highest threshold for removing nickel by that organism. It helps to prevent the nickel poisoning in the soil and helps in increase in the growth of the crops in that soil.
