Answer:

Phagolysosomal fusion

Explanation:

Macrophages ingest the bacteria through a process called phagocytosis. The phagosome undergoes a series of acidification steps where it fuses with endosomal compartments and encounters  bactericidal and antigen processing molecules. Ultimately, it will fuse with the lysosome (phagolysosomal fusion) where it encounters more acidification, hydrolases and bactericidal molecules which may kill the bacteria.

The answer would be survival of the fittest.

This metaphor, "<em>survival of the fittest</em>," was used by Herbert Spencer to explain <em>natural selection. </em>It is sometimes also referred to as the survival for existence. This phrase came from the Dawinian theory of evolution where he explains that all species are capable of producing many offsprings. However, the survival of those offsprings depends on their ability to adapt to the risks and opportunities of the external environment. 
<em>
</em>This relates to your scenario in the sense that fish lay a lot of eggs in the beginning but not all of them would live to achieve maturity. This is because even as eggs, they have many predators and are exposed to other elements. The threat pushes on even if they are able to hatch and grow up.
