Answer;

B. Periodic drought causes an abrupt decrease in vegetation.

Explanation;

-Density-independent factors are those factors limiting the size of a population whose effect is not dependent on the number of individuals in the population, such as weather and climate, exert their influences on population size regardless of the population's density.

-The density dependent factors on the other hand are factors whose effects on the size or growth of the population vary with the population density. There are many types of density dependent limiting factors such as; availability of food, predation, disease, and migration.

When microbial action during decomposition in aquatic ecosystems removes too much oxygen, the body of water experiences .
pashok25 [27]

The body of water experiences eutrophication.  

The process of eutrophication takes place primarily in ecosystems with gradual changing waters, mainly in deep lakes. In the depths of the lake, where deposition of dead algae takes place, the aerobic bacteria, which feeds on them proliferate that in turn consumes more amount of oxygen.  

Though in the absence of enough circulation of water that is usually found in the case of deep lakes, the bottom of the lake is poorly oxygenated and the bacteria eventually deplete the oxygen found in the deep layers of water. Thus, they can no longer degrade all the dead organic matter and gets accumulated in the sediments. The lake is now considered to be aging.
