Extinction, maybe?
The first life on earth was unicellular organisms. These organisms reproduced asexually, meaning that they reproduced by copying themselves. Because they did not interbreed, a slight mutation in the DNA caused a new species to exist. If one of the mutant cells failed to divide, that was a species becoming extinct. Humans cannot even begin to fathom the number of these species there must have been or when they started to become extinct. Extinction is a natural process and cannot be stopped; when we talk about being concerned about extinction we generally mean extinctions caused by modifications made to the environment by humans.
repduction
yes it is or i may be wrong research it before writing it down
natural selection.
Unicellular organisms may protect themselves from extinction through a process called binary fission, where they reproduce by dividing into two identical daughter cells. By reproducing regularly and quickly, unicellular organisms can increase their population size and ensure survival. Additionally, some unicellular organisms can form resistant structures or cysts to survive harsh environmental conditions.
phagocytosis is the process of aquiring nutrition in unicellular organisms
NO NYCgirl_1 edit: Unicellular organisms reproduce asexually but creating an exact replica of their nucleus and split in half. A very famous example of this is Ameobas. They split directly down the middle creating a clone of themselves, and therefore reproducing asexually
Mitosis
Extinction, maybe?
The process in which a unicellular organism divides to form two smaller cells is called binary fission. This process involves the duplication of genetic material and splitting of the cell into two daughter cells. Binary fission is a common method of reproduction in unicellular organisms such as bacteria and protists.

The process of drinking by unicellular organisms is called pinocytosis. Cells take in drops of liquid outside the cell. They take in meager drops of extra-cellular fluids.
They go through a process called mitosis in which they make copies of their DNA and then divide into two separate organisms. And this just keeps repeating.
reproduction
Budding is one method unicellular organisms use to reproduce. Essentially, a daughter organism begins to grow attached to the parent and eventually separates. Both parent and daughter have identical DNA. Yeasts use this method.
Unicellular organisms are able to exchange gases through their cell membrane via a process called diffusion. This allows them to take in oxygen and release carbon dioxide, similar to how multicellular organisms with specialized respiratory systems do.
