If no members of a species are alive today, that species is considered extinct. This means that all individuals have died out and there are no remaining populations to reproduce or sustain the species. Extinction can result from various factors, including environmental changes, loss of habitat, predation, or competition with other species. Once a species is extinct, it cannot return unless through de-extinction efforts, which are currently experimental and controversial.
Variations
They are all the same species
False.
Well, literally everything is alive no matter what. It is my scientific fact that this is true. I have been studying how many animals are alive today. So, pretty much everything is alive. Over 1,000,000,000,000,000 animals are alive today. Nobody knows the exact alive because every day there are new species growing everywhere.
true
no,he is very much alive! a true son of scotland.
True. The study of biology encompasses living organisms from the past and present, including fossils and extant species. This broad field examines various aspects of life, from the study of ancient organisms to the exploration of current living systems.
they won't be able to stay alive? it depends on the type or species of plant but most of the time that is true
Because nobody has found them or seen them yet
No, it is not true that geographic isolation makes it less likely for members of a species to form a new species. In fact, geographic isolation often promotes speciation, as it separates populations, allowing them to evolve independently in response to different environmental pressures. Over time, genetic divergence can lead to the development of distinct traits and reproductive barriers, ultimately resulting in the formation of new species.
The scientific name for horses is Equus caballus
No, that statement is incorrect. Competition between members of the same species is known as intraspecific competition. In contrast, interspecific competition refers to competition between different species for the same resources. Both types of competition can influence population dynamics and ecosystem structure.
