What does The rise of photosynthetic organisms do?
The rise of photosynthetic organisms helped to increase oxygen levels in the Earth's atmosphere, promoting the evolution of more complex life forms. Photosynthetic organisms also play a crucial role in the carbon cycle by converting carbon dioxide into organic compounds, which has a significant impact on the global climate.
The rise of photosynthetic organisms did not?
The rise of photosynthetic organisms did not happen suddenly, but gradually over billions of years through evolutionary processes. It led to the oxygenation of Earth's atmosphere, which allowed for the development of more complex life forms. This event has had a profound impact on the Earth's environment and ecosystems.
Why are photosynthetic organisms such as plants so important to life on Earth?
Plants are so important to life on earth because without plants the animal kingdom couldn't survive. Plants transform CO2 into oxygen which allows us to breathe They also provide us with the food we need to eat. We eat fruit, veges etc. And cows, sheep etc. eat plants to get their energy. Then we eat beef and lamb to get energy from them.
What is the role of photosynthetic organisms in the oxygen cycle?
Photosynthetic organisms, such as plants, algae, and cyanobacteria, play a crucial role in the oxygen cycle by converting carbon dioxide and water into glucose and oxygen through the process of photosynthesis. During this process, they absorb sunlight and release oxygen as a byproduct, which is essential for the survival of aerobic organisms, including humans. This oxygen is then used in cellular respiration, where it is consumed by living organisms, contributing to the overall balance of oxygen in the atmosphere. Thus, photosynthetic organisms are vital for maintaining the Earth's oxygen levels and supporting life.
Where does most of the energy used by life on earth come from?
Most of the energy used by life on Earth comes from the Sun, which drives photosynthesis in plants and other photosynthetic organisms. These organisms convert solar energy into chemical energy, forming the base of the food chain. This energy is then transferred through various trophic levels as organisms consume one another. Additionally, some ecosystems, like those around hydrothermal vents, rely on chemical energy from the Earth's interior.
What effect did photosynthetic cyanobacteria have on earth's environment?
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.

What is life's primary source of energy?
The primary source of energy for life on Earth is the sun. Through the process of photosynthesis, plants and other photosynthetic organisms convert sunlight into chemical energy that sustains all living organisms.
How many times did photosynthesis evolve in the history of life on Earth?
Photosynthesis evolved multiple times in the history of life on Earth. It is believed to have evolved at least two separate times, leading to different types of photosynthetic organisms.
Why earth has oxygen and not other planets?
Earth has oxygen because of the process of photosynthesis carried out by plants and other photosynthetic organisms. These organisms convert carbon dioxide into oxygen, resulting in the high levels of oxygen in Earth's atmosphere. Other planets may not have abundant oxygen due to different composition, lack of photosynthetic life forms, or processes that have altered their atmosphere over time.
Why is the sun very important to the earth?
inorder to sustain the life of the living organisms..
What caused a major change in the composition of Earths atmosphere?
One major change in the composition of Earth's atmosphere was the Great Oxidation Event about 2.4 billion years ago. This event led to a significant increase in oxygen levels due to the emergence of photosynthetic organisms that released oxygen as a byproduct. This change had a profound impact on the evolution of life on Earth.

Thus, photosynthetic organisms are vital for maintaining the Earth's oxygen levels and supporting life.
Where did life on earth evolve from?
Probably photosynthetic multicellular protists, such as Rhodophyta and Chlorophyta.
All life on earth is ultimately dependent on what?
The sun for energy
