Vedclass · Answer

(D) Diatoms are significant photosynthetic organisms in aquatic environments,acting as primary producers. Their cell walls are composed of silica,which makes them indestructible and leads to the formation of 'diatomaceous earth' or 'diatomite' deposits over billions of years. These deposits are often found near petroleum fields. Due to their gritty nature,diatomite is widely used in polishing agents,metal polishes,and as an abrasive in toothpastes. Therefore,all the mentioned points are correct.
