How many living organisms exists today?
It is difficult to estimate the exact number of living organisms on Earth today due to the vast diversity of life forms and the constant discovery of new species. However, scientists estimate that there are anywhere from 8.7 million to 1 trillion species currently living on our planet.
Many of the organisms living today have not been identified because they are?
small, cryptic, or live in hard-to-reach habitats. Additionally, some organisms may have unique adaptations or genetic variations that make them difficult to classify. The vastness and complexity of Earth's ecosystems also contribute to the challenge of identifying all organisms.
The earth been destroyed by a asteroid?
No, if the Earth was destroyed by an asteroid we would not be living today.
What evidence shows that organisms living millions or years ago were different from ones living today?
Yes, if it is not then technically it's not a fossil.
Why are so many organisms live on earth today?
Many organisms live on Earth today due to the planet's diverse habitats, availability of resources, and adaptability of species to different environments. Evolutionary processes have also played a role in the proliferation of diverse life forms on Earth over millions of years.

What group of organisms alive today are most similar to the first cells on earth?
Archaea are considered to be the group of organisms most similar to the first cells on Earth. They are single-celled microorganisms that have simple cell structures and thrive in extreme environments, similar to the conditions present on early Earth.
All of the living things on earth today can be grouped into what?
All living things on earth can be grouped into a foodchains.
What characteristic is most importance of the evolutionary success of organisms on earth today?
The characteristic that is of paramount importance for the evolutionary trend and success of organisms today is Adaptation.
What geologic period has fossils that closley resemble organisms living today?
Tirtiary
What is the biggest animal living on earth today?
elephant
The earth been destroyed by a asteroid?
No, if the Earth was destroyed by an asteroid we would not be living today.
Why is it so important for scientists to classify organisms both living and extinct?
It is important for scientists to classify both living and extinct organisms so that historians can know how the earth was millions of years ago and today. It is more important today so that scientists can help people preserve the earth.
What is the best definition of evolution and how does it explain the diversity of life on Earth?
Evolution is the process by which living organisms change and adapt over time through natural selection and genetic variation. It explains the diversity of life on Earth by showing how species have evolved from common ancestors, leading to the wide range of organisms we see today.
What was the first living creature on earth?
This question depends on what you mean by, "Living creature." The first single celled organisms predated bacterium and their DNA most likely contained only the most basic design. These creatures later helped form an atmosphere of CO2 and O2, paving the way for larger Oxygen-reliant organisms.
Why so many different types of organisms exist on earth today?
