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.

However, the survival of those offsprings depends on their ability to adapt to the risks and opportunities of the external environment.

</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.

Answer:
The plant hormone ABA or abscisic acid is help in regulating the guard cells via its effect on osmotically changes in turgor. ABA inhibits the proton ATPase, slow down the anion channel and other influences that result in depolarization of membrane potential guard cells that leads to efflux of the K+ closure of stomatal.
Plants have feedback mechanisms that have evolved as well. In stress conditions such as drought these mechanisms involve in closing the guard cells in order to water loss through transpiration.
