Methane is given off by animals as a waste gas.
Most animals give off carbon dioxide as a waste product for life. This is called "aerobic".
Oxygen is absorbed by the animal, and waste products are released.
Feces, urine, and carbon dioxide are all waste products of animals.
There are a handful of waste products that are products of a plant's respiration. Oxygen is one such waste product.
oxygen
The loss of oxygen from the leaf of a plant can be described as excretion because it is a waste product for the plant. During photosynthesis, plants produce oxygen as a byproduct which is then released into the environment. This process is analogous to excretion in animals where waste products are eliminated from the body.
Most animals defecate. The species that do not have alternate ways of disposing of waste materials. They survive just as well as animals that defecate.
Oxygen and glucose.
The waste product of photosynthesis is oxygen.
Two waste products common to plants and animals are carbon dioxide and water. However, only plants that photosynthesize in the dark have water as a waste product.
Yes, the waste products of animals are manure and urine.
The products of photosynthesis are glucose and oxygen. Many people consider oxygen a waste product. However, plants need oxygen just like animals and other organisms do in order to carry out aerobic cellular respiration. So oxygen is really not a waste product of photosynthesis.
