Which feature of insects aids in their massive population growth?

The feature that contributes significantly to the massive population growth of insects is their high reproductive capacity. Insects are known for their ability to reproduce rapidly and in large numbers. A single female can lay hundreds or even thousands of eggs in her lifetime, depending on the species. This trait allows insect populations to increase exponentially in a short time under favorable environmental conditions.

The high reproductive capacity enables insects to quickly exploit available resources and adapt to changing environments. This characteristic is especially advantageous in environments where conditions can change rapidly, as it allows insects to repopulate and maintain their populations despite fluctuations in food availability or predation pressures.

This feature is distinct from the other options: while longevity, predator avoidance, and the ability to fly can certainly enhance survival and distribution, it is primarily the high reproductive capacity that drives the stunning rates of population growth observed in various insect species.
