What is earth and life science?
Earth and life science is a branch of science that focuses on studying the interactions between Earth's systems and the living organisms that inhabit it. It examines topics such as geology, meteorology, ecology, and biology to better understand how the Earth and living organisms coexist and influence each other.
Parts of the earth's air water and soil where organisms are found?
Organisms are typically found in the biosphere, which includes the land (soil), water bodies (rivers, lakes, oceans), and atmosphere (air). Within these realms, organisms inhabit various niches depending on their specific habitat requirements and adaptations.
What changes were necessary in Earth and acirc and 128 and 153s atmosphere to allow complex organisms to evolve What changes were necessary in Earth and acirc and 128 and 153s atmosphere to allow comp?
The development of oxygen-producing organisms, such as cyanobacteria, played a critical role in changing Earth's atmosphere to support complex life forms. These organisms released oxygen through photosynthesis, leading to the Great Oxidation Event, which altered the composition of the atmosphere and allowed for the evolution of more complex organisms. This increase in atmospheric oxygen also provided a protective ozone layer, shielding life from harmful ultraviolet radiation.
What came first to earth as things in the eras of the earth?
The first things to come to Earth were simple single-celled organisms around 3.8 billion years ago in the Precambrian era. These early life forms eventually evolved into more complex organisms over millions of years.
Who were the first to live on earth?
The first life forms on Earth were single-celled organisms such as bacteria and archaea that appeared around 3.5 billion years ago. These simple life forms evolved into more complex organisms over time.
How many organisms are estimated to inhabit the earth?
Upwards to the trillions.
Why About 2.0 billion years ago complex organisms began to inhabit Earth.?
About 2.0 billion years ago, significant geological and atmospheric changes occurred, including the Great Oxidation Event, which increased oxygen levels in the atmosphere and oceans. This rise in oxygen allowed for more complex biochemical processes and the development of eukaryotic cells, which are the building blocks of complex organisms. These environmental conditions facilitated the evolution of multicellular life, leading to the diversification of complex organisms in Earth's ecosystems.
What events occurred that allowed single - celled organisms to into more complex organisms at the end of the precambrian time?
the ozone layer began to develop shielding earth from ultraviolet rays, this was hypothesized that these changes allowed species of single celled organisms to evolve into more complexed organisms

Are Gamma rays harmful to earth?
Gamma rays are not necessarily harmful to the planet Earth, but to all the living organisms that inhabit it, as Gamma is a powerful form of radiation.
What percent of the earth's total thickness do we inhabit?
we inhabit 89% of earth's thickness
What changes were necessary in earth's atmosphere to allow complex organisms to evolove?
During the few billion years following the appearance of cyanobacteria, oxygen became a major gas in Earth's atmosphere. The ozone layer in the stratosphere also began to develop, shielding Earth from ultraviolet rays. These major changes in the air allowed species of single-celled organisms to evolve into more complex organisms.

In what way are all living organisms similar?
All organisms use the same genetic code.Living organisms are made of the same components as all other matter, organisms that inhabit the earth at any one time they are all assembled from a nucleic acid code
What spheres do each of the five branches of Earth Science study?
Geosphere - The Earth and its features Hydrosphere - The Earth's water, in any form Atmosphere - The "gaseous envelope" that surrounds the Earth Biosphere - The living plants, animals, and other organisms that inhabit the Earth
