âI think weâve read every single book they have.â Mark chuckled. He still wasnât ready to put the children downâWill was hanging off of one hip, his hand on Markâs shoulder as he stoically looked down at Bridget, and Mabel had nuzzled into the crook of Markâs neck with a contented sigh.
Diatoms are producers within the food chain. A unique feature of diatom cells is that they are enclosed within a cell wall made of silica (hydrated silicon dioxide) called a frustule. These frustules show a wide diversity in form, but are usually almost bilaterally symmetrical, hence the group name.
Diatoms are a type of protist, a microscopic organism. What makes diatoms remarkable is they have shells made from organic compounds and silica. These shells are left behind when a diatom dies.Diatomaceous earth is a mineral that is formed from fossilized diatom shells, and this is mined for a number of industrial purposes.The product of diatoms, diatomaceous earth, is typically used, though living diatoms are also useful.iatoms are often used to filter water, particularly water in hot tubs and swimming pools. However, a vast variety of fluids can be filtered with diatoms, including different syrups, alcoholic beverages, medicines, solvents and other chemicals.
