organelles present in single-celled organisms act in a manner similar to organ systems
The first multicellular life does not need oxygen. That is the only type of life that does not need any oxygen at all basically. It is because a lot of organisms do not need the respiratory system at all.
I'm not exactly sure what you are looking for, but the first thing that came to mind is "anarobic," which comes from the Latin prefix a- meaning "not' and arobic meaning "air." Anarobic respiration is one example of this word, where certain organisms use gasses other than oxygen to create energy--yeast is an example of this.
Plants and fish rely on oxygen for respiration, while soil contains organisms that also require oxygen for their metabolic processes. However, these organisms do not necessarily use the same air that humans breathe. The oxygen in the air is exchanged and recycled through various processes such as photosynthesis, respiration, and decomposition to support the different organisms' survival.
Rocks do not have the ability to breathe as they do not require oxygen like living organisms do. Rocks undergo natural processes like erosion and weathering, but these are non-living processes that do not involve respiration.
Oxygen is essential for the process of cellular respiration, where it helps to generate energy for our bodies. It is also crucial for the survival of aerobic organisms, as they require oxygen to produce ATP. Additionally, oxygen plays a role in various chemical reactions and processes in the environment.
for reproduction. They require a host cell to reproduce and do not have the ability to carry out metabolic processes or grow on their own.

All living organisms require water to survive. This includes plants, animals, fungi, and microorganisms. Water is essential for carrying out various biological processes such as metabolism, nutrition, and reproduction.
Essential nutrients are matter that organisms require for their life processes, including growth, development, and maintenance. These nutrients can include carbohydrates, proteins, fats, vitamins, and minerals, which are obtained from the diet for proper functioning of the body.
Most animals, including humans, require oxygen for respiration. This includes mammals, birds, reptiles, and many invertebrates. Additionally, some bacteria and fungi also require oxygen for their respiration processes.
because to carry out life processes?
Living organisms require oxygen for respiration which is essential for energy production. Additionally, some organisms like plants require carbon dioxide for photosynthesis, where they convert carbon dioxide into glucose using energy from sunlight. Other gases like nitrogen may also be used by certain organisms for various metabolic processes.
Metabolic processes that require oxygen are termed aerobic. Metabolic processes that do not require oxygen are termed anaerobic.
Because food is a source of energy and it also supplies cells with oxygen
Viruses are not living organisms and do not require oxygen for respiration or metabolic processes like living organisms do. They are essentially genetic material packaged in a protein coat and rely on host cells to multiply and survive.
Organisms require energy to carry out essential functions such as growth, repair, reproduction, and movement. Energy is needed to fuel metabolic processes that maintain life and support the organism's ability to respond to its environment. Additionally, energy is used to synthesize molecules, maintain homeostasis, and carry out cellular processes.
Metabolic processes that require oxygen are called anaerobic is false. Metabolic processes that require oxygen are called aerobic. Metabolic processes that do not require oxygen are called anaerobic.
