Simple prokaryotic organisms, such as bacteria and archaea, are believed to have been the first to develop on Earth due to the harsh early environmental conditions, like the lack of oxygen and extreme temperatures. These organisms were able to thrive in such conditions and are thought to have played a crucial role in shaping the Earth's early environment.
The Gaia Hypothesis was developed by British scientist James Lovelock in the 1970s. He proposed that the Earth functions as a self-regulating system in which living organisms and their environment interact to maintain conditions suitable for life.
The first organisms on Earth were likely single-celled prokaryotes, such as bacteria and archaea. These organisms were simple in structure and adapted to harsh conditions, such as extreme temperatures and lack of oxygen. They played a crucial role in shaping the environment and paving the way for more complex life forms to evolve.
The biosphere is the biological component of Earth where living organisms interact with one another and their environment.
Scientists believe that the first living cells on Earth were likely anaerobic heterotrophs because early Earth lacked oxygen, and these organisms do not require oxygen for their metabolism. Anaerobic heterotrophs can obtain the carbon compounds they need for energy from organic molecules in their environment, making them well-suited for the conditions of early 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.
Simple, single-celled organisms like prokaryotes, such as bacteria, likely developed first due to the early environmental conditions on Earth. These organisms were able to thrive in the primitive, harsh conditions of early Earth and played a significant role in shaping the planet's biosphere.

Chemosynthetic organisms help scientists understand how life developed on Earth by providing insights into alternative forms of energy and metabolism that can sustain life in extreme environments. Studying chemosynthetic organisms offers a glimpse into the early conditions of our planet and the potential for life to exist beyond Earth. Researchers can use this information to improve our understanding of the origins and evolution of life on Earth.
Prokaryotic organisms are basically bacteria and can be found in nearly every environment on Earth.

Organisms evolve in relation to the environment surrounding them often to their advantage. Organisms in water develop fins or propulsionary characteristics to take advantage of movement in water. Monkeys developed dexterity in feet to have 3rd and 4th hands to climb trees easily. Photosynthetic organisms take advantage of the sun to produce energy. Respiratory organisms took advantage of the products of photosynthesis. Evolution gives the appearance that the earth was made for us when in fact organisms just developed to take advantage of what the environment provided.
The Earth has a biosphere, which is the part of the Earth where life exists. This includes all living organisms and their interactions with each other and their environment. Other planets in our solar system do not have a biosphere as they lack the conditions necessary to support life as we know it.
The Earth is the planet we live on, consisting of its land, water, and atmosphere. The environment encompasses all living and non-living things on Earth, including ecosystems, biodiversity, and the interactions between them. While the Earth refers to the physical planet, the environment encompasses the surroundings and conditions that influence living organisms.
All living things on Earth can be found in the biosphere. Which is the portion of Earth that supports life. All living organisms found in an environment are called biotic factors.
Photosynthetic cyanobacteria were the first organisms to produce oxygen. The effect of their oxygen production was that the earth became an environment which was suitable for life.
