Why do newts need to lay hundreds of eggs?
Newts lay hundreds of eggs to increase the chances of survival for their offspring. Many eggs are lost to predators, environmental factors, or competition, so producing a large number helps ensure that at least some will survive to adulthood. Additionally, this reproductive strategy enhances genetic diversity within the population, which can improve resilience to changing environments and diseases.

Why is it necessary that a codling moth lays large number of eggs?
The practice has survival advantages over laying few eggs. It is similar to swarm hatching. Where so many young hatch at once that there are not enough predators to eat them all. If there were enough predators then the predators would starve when there was not a swarm available. Consequently, predator numbers are unlikely to be great enough to consume all the members of a swarm.

What might account for the wide range in number of eggs laid by the largemouth bass?
Basically - survival of the species. As with most fish, their eggs are 'nutritious snacks' for any passing predators. Laying hundreds, or perhaps thousands of eggs, ensures that at least a small number of fish will survive to adult-hood - thus perpetuating the species.
