Life on earth consists largely of microscopic life (bacteria, paramecia, etc.) and insects. All animal groups higher than insects just "fill in the empty slots".
The Earth's biosphere consists of all the regions of the Earth's crust, waters, and atmosphere where living organisms can be found. It includes a wide variety of ecosystems and habitats that support a diverse range of organisms from microscopic bacteria to large mammals.
If Earth did not have any life, its atmosphere would likely consist mostly of nitrogen, similar to the atmosphere of Mars or Venus. Volcanic activity would have likely contributed to the release of gases like carbon dioxide and water vapor. Sunlight and cosmic rays might also have influenced the composition of the atmosphere over time.
humans are mammals, so if there were no animals, the only life on Earth would be plant life
Many organisms survived or there would no longer be life on Earth. Microbes were mostly unaffected, as were insects. Other survivors include fish, crocodilians, birds, lizards, turtles, amphibians, and mammals.
The Earth consists of several layers: the core (inner and outer), mantle, and crust. The core is mainly composed of iron and nickel, the mantle is mostly silicate rocks, and the crust is a thin layer of solid rock that includes both oceanic and continental crust.
They can effect humans, dogs, cats, rabbits, goats, and mostly allthe mammals and some oter spicis
The duration of The Life of Mammals is 3000.0 seconds.
The Life of Mammals ended on 2003-02-05.
The Life of Mammals was created on 2002-11-20.
On Mars, the most advanced life form (if there is any) would be bacteria, whilst on earth mammals are the most advanced.
Humans have evolved from more primitive lifeforms stemming from the origin of life on earth, humans are mammals. Mammals carry their offspring in a womb and eventually give birth to a functional baby.
it makes it different becuz it is the only planet which has life!
