flow of both energy and matter
A. Protista:Objective evidence of their existence dates back to 1.5 billion years ago in the fossil record. Bacteria, the first group of organisms to have evolved on Earth, are not included in the list of options.
The branch of biology that deals with the study of organisms is called "organismal biology" or "organismal study." This field focuses on the physiology, behavior, ecology, and evolution of individual organisms.
The first eukaryotic organisms on earth were likely single-celled organisms such as protists, which are a diverse group of organisms that have a nucleus and other membrane-bound organelles. These organisms are thought to have evolved around 1.6-2.1 billion years ago.
No. --------- It can, through intelligent organisms with technology. If people colonized mars and made it permanently habitable/ terraformed it that would be earth reproducing.
The correct order is: Individual organism -> Population -> Biome -> Community -> Ecosystem -> Biosphere. Individual organisms belong to populations, which make up communities in a specific biome, all interacting within an ecosystem. The biosphere encompasses all ecosystems on Earth.
In the first two billion years of Earth's existence, the atmosphere underwent significant changes. Initially, it was composed mainly of gases like carbon dioxide and methane, which created a greenhouse effect and maintained high temperatures. Over time, as photosynthetic organisms evolved and produced oxygen, the atmosphere gradually transformed into the oxygen-rich composition we have today.
"Bhuvan" in Telugu can mean "world" or "earth". It can also be used to refer to an individual's existence or being.
That's a bit of a nonsense question. The existence of life is consistent with *any* and *every* hypothesis that tries to explain the existence of life, scientific or not. The existence of life is the very thing that the hypothesis is trying to explain, so necessarily the hypothesis assumes it and must therefore be consistent with it. The same goes for the *kind* of life we find on Earth: since any scientific hypothesis must explain the life we find here, such a hypothesis must necessarily be consistent with the life we find.
FYI not to the human race and its existence. to the earth and its existence. see discussion.
Earth is home to human beings and other living organisms because it has the right conditions to support life, such as a suitable atmosphere, water, and a moderate temperature range. The diverse ecosystems on Earth provide food, shelter, and resources necessary for the survival and growth of living organisms. Additionally, Earth's position in the habitable zone of the solar system allows for the existence of liquid water, which is essential for life as we know it.
when will earth be wiped out of existence? We ARE NOT the only existence in the universe.

back then 3.6 billion years ago there was no oxygen but today we have many things
The Earth's existence and natural processes are a result of various scientific phenomena and processes that have occurred over billions of years. It is not attributed to any single individual or entity.
gravity
It means something that is of the planet earth, or anything related to the earth. Can also mean an earthly existence as opposed to a spiritual existence.
