Explain why parthenogenesis could prove to be harmful to the survival of this species if it were the only method of shark reproduction.

Parthenogenesis is an asexual reproduction wherein offspring develops from unfertilized eggs. Usually, female offspring are developed from unfertilized eggs. 

Parthenogenesis is only possible in favorable environmental conditions, if conditions are not stable, then, sexual mode of reproduction is done.

If the only method for shark reproduction is through parthenogenesis then it can be harmful to the survival of the species because shark cannot reproduce unless the environmental condition is favorable. For example, environmental conditions have been unfavorable for a long time, then those sharks that are existing may slowly die without reproducing the next generation of their species, decreasing their number until the species die out.

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.two years ago, when picking flowers in the mountains back of yosemite valley; i found a book. it was blotted and storm-beaten, all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however, many of the inner pages were well preserved. and although all were more or less stained and torn; whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today, its granite pages have been torn and blurred by the same storms that wasted the castaway book.
