Diatoms and foraminifera are two groups of organisms that are key sources of food in aquatic environments and whose fossilized forms are used as a filter and as a grinding and polishing agent. Diatoms are a type of algae with unique silica cell walls, while foraminifera are marine protozoa that secrete calcareous shells.

The black substance deposited on the glass rod is likely soot, which is a carbon-based material that forms when organic matter is incompletely burned. This can occur when the glass rod is exposed to a flame or other heat source.
Diatoms, Cope pods, and Jellyfish are all forms of plankton and are the foundation of the ocean food web
Silicon dioxide forms the cell walls of diatoms, which are a type of algae with intricate and intricate silica-based cell walls.
Such a material is GLASS.
Mainly Diatoms
Yes, the disappearance of diatoms would have significant effects on other forms of life in the pond. Diatoms are a major food source for many aquatic organisms, so their absence would disrupt the food chain and impact the overall biodiversity of the ecosystem. It could lead to population declines or shifts in species composition as organisms dependent on diatoms struggle to find alternative sources of food.
