Final answer:
The question regarding the number of species on planet Fabula cannot be answered, as Fabula is not recognized in biology. However, Earth holds an extensive diversity of species, including hundreds of thousands of beetles, thousands of birds, and thousands of frogs. From an extinction rate perspective, 100,000 extinctions might be expected over a century.
Step-by-step explanation:
The planet Fabula is not a known term in biology; therefore, the question about the number of species on this planet cannot be answered. However, if we refer to Earth, we know that there are about 350,000 species of beetles, nearly 10,000 species of birds, and almost 5,000 species of frogs worldwide. Regarding the review question, with an extinction rate of 100 extinctions per million species per year (E/MSY) and an estimated 10 million species, we'd expect 1,000 extinctions per year. Over a century, that would lead to 100,000 extinctions.
