They add hydrogen (from water) to make sugars.
Yes producers use respiration.
There are a handful of waste products that are products of a plant's respiration. Oxygen is one such waste product.
Air is inhaled to use the oxygen for cell respiration. Then carbon dioxide and water (products of cell respiration) are breathed out because they are waste products.
Respiring organisms, these can be from humans such as ourselves to micro-organisms, such as bacteria. There is one 'waste' product of photosynthesis - oxygen, glucose is all used or stored by the plant. Oxygen is not a complete waste, as it is used in plant respiration, however, the oxygen released from the plant can be used in respiration in other organisms.
Producers use the products of photosynthesis, such as glucose and oxygen, to carry out their life processes. Glucose is used as an energy source for growth, reproduction, and maintenance of cellular functions. Oxygen is released as a byproduct of photosynthesis and is used in the process of cellular respiration to generate more energy for the plant.
Oxygen is the gas that animals use in respiration. Plants use both oxygen and carbon dioxide. (This is assuming you mean cellular respiration.)
Net primary productivity is the amount of energy that remains in an ecosystem after accounting for the energy used by producers (plants) for respiration. It is calculated by subtracting the respiration rate of producers from the gross primary productivity. This remaining energy is available for consumers in the ecosystem to use for growth and reproduction.
Respiration provides the body with energy by converting glucose into ATP, which is used for cellular processes and overall metabolism. It also helps in removing waste products like carbon dioxide from the body.
Respiration and fermentation which make up photosynthesis.
The word aerobic means to use oxygen while anaerobic doesn't need oxygen. The products of aerobic respiration are carbon dioxide and water and energy (ATP). The products of anaerobic respiration are oxygen and energy (ATP).
Humans primarily use aerobic respiration for energy production because it is more efficient and produces more energy compared to anaerobic respiration. Aerobic respiration also allows for the sustained production of energy over longer periods of time, making it ideal for activities that require endurance and stamina. Additionally, aerobic respiration produces fewer waste products, such as lactic acid, which can cause muscle fatigue and soreness.
Decomposers, such as bacteria or fungi, break down waste products and dead organisms to return matter to the physical environment. Producers can then use this matter to build their bodies, starting the cycle of matter again.
