I think you question is a little confused try these answers or ask again. The purpose of respiration is to release energy from food molecules. The purpose of photosynthesis is to use sunlight energy to synthesis glucose (a food molecule).
Oxygen.
Used oxygen (carbon dioxide) and used food (feces).
Photosynthetic organisms are those that capture solar energy and release oxygen through the process of photosynthesis. Some examples include plants, algae, and cyanobacteria.
The gas produced by photosynthesis is oxygen. It is released into the atmosphere as a byproduct of the process, where it can be used by other organisms for respiration. Oxygen is essential for the survival of most living organisms.
Photosynthetic organisms, such as plants, algae, and cyanobacteria, play a crucial role in the oxygen cycle by converting carbon dioxide and water into glucose and oxygen through the process of photosynthesis. During this process, they absorb sunlight and release oxygen as a byproduct, which is essential for the survival of aerobic organisms, including humans. This oxygen is then used in cellular respiration, where it is consumed by living organisms, contributing to the overall balance of oxygen in the atmosphere. Thus, photosynthetic organisms are vital for maintaining the Earth's oxygen levels and supporting life.
It would be impossible for oxygen requiring organisms to exist before photosynthetic organisms because there was not oxygen in the atmosphere for these organisms to breathe. Photosynthetic organisms take carbon dioxide and water in and create oxygen as waste. Before these photosynthetic organisms existed there was not enough or any oxygen in the atmosphere for organisms requiring oxygen to survive.
Food and Oxygen
Organisms which need oxygen are called aerobic organisms or aerobes. The oxygen is used in the process of respiration to release energy from food. Organisms which do not use oxygen in respiration are called anaerobic organisms or anaerobes. See: http://en.wikipedia.org/wiki/Aerobic_organism
Used oxygen (carbon dioxide) and used food (feces).
Oxygen is essential for most living organisms because it is used in the process of cellular respiration to produce energy. Organisms use oxygen to break down food molecules and generate ATP, the energy currency of cells. Without oxygen, many organisms would not be able to carry out this vital process and would not survive.

Oxygen is needed by most living organisms for cellular respiration, where it is used to break down food molecules to release energy. This energy is essential for various life processes, including growth, reproduction, and movement. Oxygen also plays a crucial role in ATP production, the primary energy currency of cells.

Nitrogen is used in various industries such as food packaging, electronics manufacturing, and pharmaceuticals. Oxygen is essential for respiration in living organisms and is also used in medical applications, welding, and steel production.
The products of photosynthesis, such as glucose and oxygen, are used by other organisms as a source of energy. Glucose is a key source of energy for many organisms, including plants, animals, and bacteria. Oxygen is used by animals for respiration to produce energy.
Producers are plants that give us oxygen, and vegetables and fruits. Producers don't eat other producers and organisms, they only get eaten, or used as food by other organisms.
Oxygen is essential for respiration in organisms, allowing them to break down food molecules to release energy. Carbon dioxide is a byproduct of this process and is used by plants during photosynthesis to produce oxygen and energy-rich sugars. This cycle of oxygen and carbon dioxide exchange between organisms maintains the balance of gases in the atmosphere, crucial for supporting life on Earth.
