The bacteriostatic antibiotics can be defined as those antibiotics, which prevents the growth of bacteria. These keeps the growth of bacteria in the stationary phase so that bacteria cannot cause harm to the host.
The bactericidal antibiotics can be defined as those antibiotics, which kills the bacteria.
The example of bacteriostatic antibiotic is Tetracycline that it inhibit the bacteria ribosome production of proteins. This way bacterial growth and reproduction will get restricted.
The example of bacteriocidal antibiotic is polymyxin B. It causes injuries to the plasma membrane of the bacteria which can be lethal for bacteria.

Answer:
The correct answer is C) benthic ocean
Explanation:
Sun is the ultimate source of energy for almost all the organisms present on the earth. The organism that especially lives on land are highly dependent on solar energy because all the plants and most algae require sunlight to make their food and they are the primary produces on which other organism are dependent.
Benthic ecosystem are the ecosystem that is present at the very depth of the ocean or on the ocean floor. So in that much depth, there is very little or no penetration of sunlight occurs. So the ecosystem there does not directly depend on sunlight for there survival. So they benthic ocean ecosystem would likely survive the longest.
