No. It is not necessary for EVERY member of a species to reproduce in order for the species to survive. Consider humans. Some are infertile and can't reproduce, and some choose not to reproduce, yet the human species survives.
the organism has to reproduce otherwise the species will go extinct.
An organism is a particular type of living thing that can breed and reproduce. It can be a complex multicellular organism like a plant or animal, or a simpler unicellular organism like a bacterium. The ability to reproduce is a defining characteristic of living organisms.
Yes. All species of organism reproduce. If they didn't reproduce they wouldn't exist.
One kind of organism is a species.
Species
An organism's biological imperative to reproduce is driven by the need to pass on its genetic material to the next generation and ensure the survival of its species.
Species
An organism that shares physical characteristics and can reproduce is known as a species. Members of a species typically have similar traits due to common ancestry and can interbreed to produce viable offspring. For example, domestic dogs (Canis lupus familiaris) share distinct physical characteristics and can reproduce with one another, leading to various breeds within the same species.
If their species is going extinct they can reproduce by them self.
The species Gene Pool which results from mostly its habitat and how much it needs to reproduce.
The term for the length of time that an organism of a particular species usually lives is "lifespan." It refers to the duration of life for an individual from birth to death, which can vary between species.
Reproduction. An individual organism does not have to reproduce in order to survive but if the organisms did not produce then the species would die out after just a single generation.
