Everyone will be exactly the same as their parent. Organisms that reproduce asexually, cells for example, create a genetic copy of themselves. Where as organisms that reproduce sexually, humans for example, get their genes from both parents and end up being a unique combination of their parents.
it becomes extinct
There are tons of organisms that reproduce asexually. As for ANIMALS - A lot of species of fish do (some sharks partake in parthenogenesis - a type of asexual reproduction), some species of wasps, whiptail lizards, sea anemones, coral, starfish, snails. All fungi, bacteria, Archaea, Protist and amoebas reproduce asexually. Some plants are capable of reproducing asexually, such as strawberry, onions and potatoes.
All the Coelenterates that I know of (jellyfish, sea anemones, etc) and some Platyhelminthes (flatworms). There are undoubtedly others, but I can't think of them offhand.
Some organisms have evolved to reproduce asexually due to the fact they may not be in a stable enough environment for them to reproduce sexually. Often times the population of an organism will be smaller if they reproduce asexually and they will have a much small gene pool.
By cellular reproduction. Cells reproduce asexually so if there is only one cell and it reproduces then there will be two cells and thus multicellular.
All organisms must reproduce.
No. Platypuses are mammals, and all mammals reproduce sexually, not asexually.
All monkeys reproduce sexually and none reproduce asexually.
No, animals either reproduce sexually or asexually. In sexual reproduction, two parents are required and an offspring is born with inherited genes/characteristics of both parents. In asexual reproduction, only one parent is required to produce an offspring and that offspring has all the characteristics of the parent. Humans reproduce sexually, whereas single-celled organisms like amoebas reproduce asexually.
Mostly sexually, but some insects can reproduce asexually, such as the aphid

No.
Teacup pigs reproduce sexually. All animals reproduce sexually. Only plants have the ability to reproduce asexually.
No, biological species concept is NOT useful for extinct organisms at all, nor organisms that reproduce asexually; it is only useful for organisms that produce sexually.
No. Amphibians reproduce sexually, as all vertebrates do.
If reproduce means producing offspring/copies of itself, then yes. If reproduce means reproducing sexually (not asexually), then no. Bacteria reproduce through asexual reproduction -- making exact copies of themselves.
if your asking how cells reproduce they can usually reproduce asexually[all by themselves].
Animals reproduce sexually not asexually. They have to have two animals to procreate, including both a male and a female.
