When organisms are found in small numbers, it is referred to as being "rare." This term can apply to species that have low population densities in their natural habitats, often due to factors like habitat loss, environmental changes, or limited distribution. Rarity can also influence conservation status, as rare species may be more vulnerable to extinction.

A small one-celled organism is called a microorganism or a single-celled organism. Examples include bacteria, archaea, and some protists.
A small bit of nucleic acid found in the nuclei of all living cells is called DNA (deoxyribonucleic acid). DNA contains the genetic instructions necessary for the growth, development, functioning, and reproduction of an organism.
Tissues are connected to the cells organism by small molecules called cells.
Because micro means small and a single celled organism is typically rather small.
If a species is endangered, the organism will be found in very small numbers.

A very small living thing is called a micro organism or a microbe, micro organism can be spelt with a hyphen (-) or just as two words, a living thing is called an organisms
Globigerina is a type planktonic Foraminifera (a single celled organism with a small shell) that are found in the world's oceans.
The small brown long bug commonly found in gardens and fields is called a centipede.
Irrational number are NOT called surds. For example, pi is irrational but it is not a surd.Surds are a very small subset of irrational numbers.
