Explanation:
Phytoremediation is a process of the bioremediation that uses different plants to transfer, remove or destroy the contaminants from the soil. Cd is one of the contaminants that are removed or destroyed by the process of the phytoremediation.19 mg/kg soil is the concentration was available in the soil prior to the phytoremedaition took place.
Thus, the correct answer is - option B.
<h3><u>Similarity and differences of carbon cycle in the ocean as on land:</u></h3>
- The Carbon Cycle is a biogeochemical cycle by which Carbon circulates around the planet.
- Carbon Cycle just like other cycles compromises of sequence of events that are essential to make earth capable of sustaining life.
- In land carbon is mostly circulated through photosynthesis and stored in living as well as non-living organisms.
- In oceans carbon is absorbed and dissolved into the water and get used by animals and plants.
- Ocean is like a giant sponge that soaks up more carbon than it gives.
- Like on land photosynthesis too occur in oceans and get incorporated into marine and terrestrial organisms as organic matter.
