A. simple
Explanation:
Asexual reproduction is mainly used by bacteria or small organisms that are too simple to have created a mechanism for sexual reproduction. The advantage of sexual reproduction is the recombination--why do you think you're not an exact copy of your parent? That's because they didn't have you via asexual reproduction.
Why not B: This is the opposite.
Why not C: This isn't necessarily a requisite condition; many bacteria do not live underwater.
Why not D: This is certainly wrong. Bacteria are not extinct, and not looking to be so anytime soon.
Answer:
Some animals weather rocks by scraping them as they feed. Other animals change Earth's surface by burrowing into it and moving material. Too many animals in one place can destroy most of the plants, leading to faster erosion.
If too many animals graze the same land area, the animals’ hooves pull plants out by their roots. A land is overgrazed if too many animals are living there. Grazing animals can cause erosion if they are allowed to overgraze and remove too much or all of the vegetation in a pasture.

It would be the last one. ' enables an organism to survive and reproduce.'
