Life is sustained on Earth, from a scientific stand point it is a delicate balance of nature. The right amount of heat and cold, sun and dark, water and dryness, the changing of the seasons, the rotation of the earth, there are a million different tiny aspects that make life possible and all of those things have to line up perfectly for it to be possible.
From a Christian stand point God created the above laws of nature thereby sustaining life on Earth. The delicate balance is proof of a creator.
If you mean living processes, then the answer is Sunlight. If you mean geological processes, then the answer is decay (nuclear fission) of radioactive isotopes in the Earth's core and Sunlight. If you mean tidal processes, then the answer is kinetic (rotational) energy transfer.
Biogeochemical cycles are crucial for sustaining life on Earth as they regulate the flow of essential elements such as carbon, nitrogen, and phosphorus between living organisms and the environment. These cycles ensure that nutrients are recycled and available for plants and other organisms to use, forming the basis of all ecosystems and supporting life on our planet.

The human body can sustain a blood loss of up to 15-30 before it becomes life-threatening.
Photosynthesis is critical as it converts sunlight, water, and carbon dioxide into glucose and oxygen, providing energy for plants and releasing oxygen into the atmosphere. This process is the foundation of the food chain, as plants are the primary producers that support all other life forms. Without photosynthesis, the Earth would not have enough oxygen and energy to sustain life as we know it.
Stars are suns and cannot sustain life. Earth is well, earth, and it CAN sustain life.
we can sustain life on earth if we keep on recycling and pick up rubbish.
While Earth can no doubt sustain life in the case of humans and every animal alive to date, it is still a question as to whether earth can sustain life or not.
star is a huge mass of gas, where as earth is a planet
Apart from water, you need oxygen in the air to sustain life on earth. With these two indispensable features, both mankind,animals and botanical reserves sustain life on this planet.
Three interconnected factors that sustain life on Earth are the presence of liquid water, a suitable atmosphere with the right balance of gases for respiration, and the Earth's distance from the sun to maintain a habitable temperature range.
Gravity provides the centripetal force to sustain orbits, F= mGM/r2
No planet except the planet Earth is known to sustain life till date.
Earth is the only planet in our solar system that can sustain human life.
To sustain life, a planet must have oxygen and a variety of gases, plant life, strong enough gravity and enough clean water.
Earth can sustain life. The Moon can not.
Also called "atmosphere", which is a layer of gases held in place by the Earth's gravity, that protects life by absorbing ultraviolet radiation, warming the surface through heat retention, and reducing temperature extremes to sustain all life on Earth.
