Final answer:
Vegetative reproduction is the production of offspring from the nonsexual tissues of a parent, which is a form of asexual reproduction resulting in genetically identical offspring. Sea stars can regenerate from fragments, effectively a form of asexual reproduction. Animals with limited mobility that reproduce sexually might utilize fragmentation or budding if needed.
Step-by-step explanation:
Production of offspring from the nonsexual tissues of a parent is called vegetative reproduction. This form of asexual reproduction is common in plants, resulting in offspring genetically identical to the parent. In animals, similar processes can occur through fragmentation, where a part of the organism can grow into a new individual. For instance, when sea stars are broken apart, they often reproduce by regeneration, with the separated parts growing into new sea stars, effectively doubling their numbers.
For a sexually reproducing animal with limited mobility, a possible form of asexual reproduction could be fragmentation or budding. These methods ensure the survival of the species when sexual reproduction is not viable due to restricted movement or the absence of a mate.
