What characterizes organisms with simple life cycles?

Organisms with simple life cycles are typically characterized by the fact that they remain in one habitat throughout their life cycles. This means they do not undergo complex developmental changes or migrate between different habitats, allowing them to thrive in a specific environment. These organisms usually have a straightforward life cycle that does not involve significant changes in form or habitat throughout their development.

In contrast, organisms with multiple metamorphoses (like many insects) experience substantial changes in form and often occupy different habitats at various life stages. Additionally, migration suggests a more complex life strategy involving movement between distinct habitats, which is not typical of simple life cycles. The idea of having no defined adult or juvenile stages refers to organisms that might exhibit more continuous growth rather than distinct stages, which can also complicate their life cycle beyond the simplicity described in this context.
