What is the importance of oxygen (O2) in sustaining life on Earth?
Oxygen (O2) is crucial for sustaining life on Earth because it is essential for the process of respiration, where organisms use oxygen to produce energy. Without oxygen, most living organisms, including humans, would not be able to survive. Additionally, oxygen plays a key role in the Earth's atmosphere by helping to regulate the planet's temperature and supporting the ozone layer, which protects life on Earth from harmful ultraviolet radiation.
What is always present in the atomosphere?
Oxygen is a gas that is always present in Earth's atmosphere. It makes up about 21% of the air we breathe and is essential for sustaining life.
What is the importance of O2, also known as oxygen, in sustaining life on Earth?
Oxygen, also known as O2, is crucial for sustaining life on Earth because it is essential for the process of respiration in living organisms. Organisms use oxygen to convert nutrients into energy through cellular respiration, which is necessary for growth, metabolism, and overall survival. Without oxygen, most living organisms, including humans, would not be able to survive.
Which process gives off oxygen into the air?
Photosynthesis is the process by which plants and other organisms convert light energy into chemical energy, releasing oxygen as a byproduct. This process is essential for sustaining life on Earth as it replenishes the oxygen in the atmosphere.
Why are the elements carbon, hydrogen, oxygen, and nitrogen important for sustaining life on Earth?
Carbon, hydrogen, oxygen, and nitrogen are important for sustaining life on Earth because they are essential elements found in all living organisms. Carbon is the building block of organic molecules, hydrogen and oxygen are crucial for energy production and cellular processes, and nitrogen is necessary for the formation of proteins and DNA. These elements play key roles in the structure and function of living organisms, making them vital for life as we know it.
What does the atmosphere surrounding earth provide oxygen for?
The atmosphere surrounding Earth provides oxygen for living organisms to breathe and carry out cellular respiration, which is the process that releases energy from food. This oxygen is essential for sustaining life on Earth.

How are the carbon oxygen and nitrogen cycles vital to sustaining life on earth?
The carbon, oxygen, and nitrogen cycles are vital for sustaining life on Earth because they ensure that these elements are continuously recycled and available for organisms to use. Carbon is essential for building organic molecules, oxygen is necessary for respiration, and nitrogen is a key component of proteins and DNA. Without these cycles, life as we know it would not be able to thrive.
Which substance in atmosphere and their combinations are essential for life on earth?
Oxygen, carbon dioxide, nitrogen, and water vapor are essential substances in the atmosphere for life on Earth. These gases provide the necessary components for respiration, photosynthesis, and the water cycle, which are vital processes for sustaining life on our planet.
What is the most important element found on Earth?
The most important element found on Earth for sustaining life is oxygen. It is essential for respiration in organisms, including humans, and plays a crucial role in various biochemical processes.
How can you use the word essesntial in a sentence?
Water is essential for sustaining life on Earth.
What are the three sources of life?
The three main sources of life are air, water, and sunlight. Air provides oxygen for respiration, water is essential for hydration and metabolism, and sunlight is crucial for photosynthesis in plants. These sources are essential for sustaining life on Earth.

What group is oxygen?
Oxygen is a non-metal element and belongs to Group 16 (formerly Group VIA) of the periodic table. It has the atomic number 8 and is essential for sustaining life on Earth.
What is the importance of oxygen in sustaining life?
Oxygen is essential for sustaining life because it is needed for the process of cellular respiration, which provides energy for all living organisms. Without oxygen, cells would not be able to produce the energy needed to carry out their functions, leading to the death of the organism.
