No, it is not. In many branches of science it is necessary to deal with numbers which are very large or very small and scientific notation is used to represent such numbers more easily.
It is not always necessary. Scientific notation (also called standard form or exponential notation) is a way of writing numbers that accommodates values too large or small to be conveniently written in standard decimal notation.

Scientific notation is useful for writing moderately large and small numbers. But, even that will not cope with the seriously big numbers.
For a product to be calculated, two or more numbers are necessary.
It isn't technically necessary; it is used for convenience, to avoid using very small or very large numbers.

Large numbers of gametes are necessary in spawning to increase the probability of successful fertilization. By releasing many gametes, the chances of at least some of them encountering and fertilizing another gamete are improved, increasing the likelihood of successful reproduction. This strategy helps compensate for external factors such as water currents that can disperse gametes widely.
Obviously "large numbers"
It is necessary to have a strong military force with a large empire.
Yes, either that or some other system for housing large numbers of prisoners. But, as it was the Nazis who were in power they would chose who to imprison, and perhaps were unjust in their choice.
No.
No, it's not necessary.
They are capable of reproducing in large numbers because they have spores
When dealing with very large numbers or very small numbers where a relatively small number of significant figures are required.
The numbers of large canivores in the desert are low as the biome cannot support large numbers of them. There is not enough food to feed large numbers of carnivores so they are rearely seen.
