some organism undergone extinction because they compete for their neccesities and territory.
Extinction.
An extinction event.
This term is extinction.
Extinct (Extinction)
The extinction rates of terrestrial and freshwater organisms varies per location. This is largely dependent on other growing and declining populations.
The process in which groups of organisms die out is called extinction. Extinction occurs when a particular species cannot adapt to changing environmental conditions or faces competition from other species, leading to their eventual disappearance.
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.
Cretaceous-Paleogene extinction event was one of the most important events in Earth history. When a massive asteroid fell on the coast of Yucatan in modern Mexico it eradicated about half of all animal species, including the dinosaurs. But many of other organisms, such birds, survived. Also survived many organisms with light mass: early mammals, insects, some reptiles, etc.
Extinction
The extinction of so many organisms left a large ecological niche to expand into, which mammals did.
The disappearance of all organisms of a specific species would be called extinction. This event can have significant ecological impacts on the ecosystem that the species once inhabited.
