Water (H2O), carbon, and oxygen. Water is the functional carrier of life processes, carbon is the building block, along with hydrogen from the water and free oxygen for respiration.
There are "anaerobic" bacteria that live in environments on the Earth, but these use the same amino acids as other life. Instead of oxidation, these organisms use fermentation or other processes to obtain energy. There are also bacteria that use sulfates instead of ordinary oxygen.
Lifeforms not based on carbon and oxygen are subjects of speculation, but are unlikely for several reasons, and have never been observed.

What is the chemical formula for seawater?
mainly composed of a NaCl solution with most of it just being H2O if you disregard the organisms that live within it
What do chemical reactions in living organisms need to start?
Chemical reactions in living organisms require a source of energy to start. This energy is typically obtained from molecules such as ATP. Additionally, enzymes play a critical role in catalyzing these reactions by lowering the activation energy required for the reaction to occur.
Why do living organisms need living space?
Living organisms need living space for various reasons, such as access to necessary resources like food, water, and shelter, to escape competition from other species, to find mates, and to raise offspring. Limited living space can also lead to overcrowding, increased stress, and conflict among organisms.
Do all organisms need air to survive?
All living organisms need water to survive, because they have cells. With air, not all living organisms need air. Some forms of bacteria do not need oxygen to live, and others can't stand oxygen.
What organisms doesn't need sunlight to survie?
Organisms that do not need sunlight to survive include deep-sea hydrothermal vent bacteria, some fungi living in caves, and certain types of chemosynthetic bacteria that derive energy from chemical reactions in extreme environments. These organisms have adapted to thrive in conditions where sunlight is not readily available.
What is the key ingredient that all organisms need?
All organisms need oxygen to live.
How do organisms get the energy they need in order to live?
you need to smell
What is the fuel need by organisms to live called?
carbondiyoxide
Why do you need to know what organisms lived long time ago?
why do we need to know what organisms live long time ago
Why do organisms need the chemical buliding blocks of cells?
I dont know who cares
What do all organisms need in the place where they live?
food they all need food
What 3 things organisms need to survive?
All organisms need food, water, and shelter in order to live, grow, and reproduce.
What do Earth organisms need to live and reproduce?
Earth organisms need essential nutrients, water, oxygen, suitable temperature, and an energy source to live and reproduce. Additionally, shelter or habitat plays a crucial role in providing a safe environment for organisms to thrive.
Is all organisms need energy to survive a scientific theory?
Yes they can just lile humans need to brerth to live organisms are living things
What are organisms that live in hydrothermal vent?
There are some organisms that make there own food and that don't need vitamins from the sun.
Which organism does not require sunlight to live?
there are many organisms that do not require sunlight to live but then there are some that need hosts
What four things do living organisms need to live?
Air,Food,Water
