Your's do (i.e. animals), but plants do fine on just on water and CO2 and sunlight.
Some bacteria use sulfur instead of oxygen.
Cellular respiration is the process by which cells convert glucose and oxygen into energy, carbon dioxide, and water. This process occurs in the mitochondria of cells and is essential for providing the energy needed for various cellular activities.
Prokaryotic cells can be aerobic (requiring oxygen) or anaerobic (not requiring oxygen), while eukaryotic cells typically require oxygen for aerobic respiration. However, some eukaryotic cells can also perform anaerobic respiration in the absence of oxygen.
Plants make their own food through a process called photosynthesis, where they convert sunlight into energy. They also absorb water and nutrients from the soil through their roots. Plants use this energy to grow, reproduce, and carry out their metabolic functions.
No, not all forms of life on Earth require oxygen in their environment. There are forms of life, called anaerobic forms, that do not require oxygen. These animals belong to the phylum Loricifera.
Plant cells need water, sunlight, carbon dioxide, and minerals from the soil to carry out photosynthesis and produce energy. They also require oxygen for respiration and growth. Additionally, plant cells rely on hormones for growth regulation and defense mechanisms against pathogens.
we know that we all need oxygen to live , we can live without food for 3 to 4 days and also water 2 to 3 days but the the first and the foremost thing that we need to live is oxygen .this oxygen is stored in some particular cells called the cytoplasm . these cells help plants prepare there food and if this cells are damaged then there is not fresh and pure air we can breath, hence this required.

You will need a number of things to live in space such as oxygen, food, water, and clothes
No, we also need food, water, and oxygen.

Simply saying heart is a pumping organ , which pumps blood into the whole part of the body. The oxygen from lungs dissolve in it and the cells get oxygen through this circulation of blood. Food get digested and cells get food through the blood. thus the cells live with the help of heart. Our body is made up of cells and the cells live with the help of heart means the whole body live with the help of heart
Animals without blood, such as sea sponges, obtain oxygen and nutrients through diffusion. They rely on their porous body structures to allow oxygen and food particles to diffuse in and waste products to diffuse out. This process occurs through direct contact with their environment.
