I believe it is B. 1.7 million. Although there are millions of species only about 1.7 to 2 million are actually known to science

Answer:

The correct answer is B. 1.7 million.

Earth is home to a vast array of living organisms, with an estimated 1.7 million species currently known to science. This number represents only a fraction of the total number of species that actually exist on our planet. It is believed that there could be anywhere from 8.7 million to 30 million species in total, with many still waiting to be discovered and described by scientists.

The diversity of species on Earth is truly staggering, from microscopic bacteria to gigantic whales, and from tiny insects to towering trees. Each species plays a unique role in its ecosystem, contributing to the balance and functioning of the natural world. The study of these different species helps scientists understand the complexities of life on our planet and how all living organisms are interconnected.

Conservation efforts are crucial in protecting the incredible diversity of species on Earth. By safeguarding habitats, preventing the extinction of species, and promoting sustainable practices, we can ensure that future generations will also have the opportunity to marvel at the vast array of life forms that call our planet home.
