False. The full extent of Earth's biodiversity has not always been known. Our understanding of biodiversity has gradually evolved over time through scientific research and exploration. It was only in recent centuries that scientists began to uncover the true extent of Earth's biodiversity through observations and catalogs of different species. Furthermore, new species are still being discovered and documented to this day, indicating that our knowledge of biodiversity is an ongoing process.

True. It is true that we have known for a long time that biodiversity on Earth is vast. Earth is home to a wide range of ecosystems, species, and genetic variation, making it one of the most diverse planets in our solar system.

True. We have known for a long time that Earth possesses a vast amount of biodiversity. However, the full extent of Earth's biodiversity is still not completely understood, and new species are continually being discovered. The knowledge of Earth's biodiversity has been accumulated through scientific research conducted by experts in various fields, such as biology, ecology, and taxonomy. These experts explore and study different ecosystems, conduct surveys, analyze data, and document the diversity of species found in different regions and habitats on Earth. Their observations and findings contribute to our understanding of the immense biodiversity present on our planet.
