No, some men are sterile and some women have ovarian cancer.
However, our species still lives on because we can count on other men and women to reproduce!
If a species should be endangered or rare, one member not being able to reproduce may make a huge impact on the on living of that species.
In theory yes, but in real life some specimen may be unable to reproduce because of a disease, injury etc. That doesn't exclude them from being a part of the species.
the ability to reproduce
No. Otherwise Catholic priests would really be in trouble. :) Actually, some organisms will die soon after they have reproduced. In fact, mating is really bad idea if you're a male redback spider because your female partner kills you during copulation and will often eat you once she's finished!
No, it is not necessary that all members of a species must be able to reproduce. In species of insects like ants and bees in particular, very few (one per colony) can actually produce eggs. Example:Queen bee Yes of course every birth matters to an animal species especially endangered species such as mountain gorillas and giant pandas. In higher organisms like vertebrates and some invertebrates, reproduction is the method of continuing their lineage.
Reproduction is one of the basic characteristic that every living organism show.Population of a species is maintained by method of reproduction.Living organisms give birth to offspring's by reproduction.
The death of every member of a species is called extinction. When a large number of different species is dies out at the same time it is called mass extinction.
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.
Not necessarily.Take the example of Homo sapiens (Human beings).Around the world, a LARGE number of women may be infertile (cannot reproduce) or will not be willing to reproduce.Despite the fact that many do not reproduce, you continue to see many human beings.
Pretty much every living species has the urge to reproduce. If it hadn't had that, the species would have died out.
Simple - they reproduce to perpetuate the species ! If they didn't - every species would die out !
the ability to reproduce
extinction
They must be able to reproduce, however a large percentage of the offspring never reach sexual maturity and only a smaller percentage of those will reproduce in many cases.
Because every species (including humans) is genetically programmed to reproduce ! The only way for a species to reproduce is by the combining of male and female cells to create a zygote.
Once every 21 days a Saanen goat can reproduce. This is the same reproduction rate for all the different species of goats.
They may become extinct, without human intervention (e.g. invitro fertilization)
