Answer: D
-Explanation-
Changes in abiotic factors can result in extreme problems for some organisms.
For example, if a plant is adapted to low temperatures and the specific are where it lives, has a change in its temperature(thanks to global warming!), this plant will die and this area will no longer support life, which is due to the change in abiotic factor (temperature).
It can also have positive effect on organisms.
For example, due to different reasons(like water pollution), water becomes enriches in mineral thus supporting large population of algae,causing water blooms. It does have negative effect on plants, fish and other organisms in water but, algae ha a positive effect of this change in abiotic factors(water).
