The correct answer is: an increase of biodiversity.<br /><br />The abrupt appearance of new organisms is an example of an increase of biodiversity. Biodiversity refers to the variety of life forms in a particular habitat or ecosystem. When new organisms suddenly appear, it indicates an increase in the diversity of species within that habitat or ecosystem. This can happen through various processes such as evolution, migration, or introduction of new species.
