Most animals give off carbon dioxide as a waste product for life. This is called "aerobic".
A waste product that a plant releases after it makes food is oxygen. Other organisms depend on this oxygen to survive.
Oxygen is an important by-product (not waste) of photosynthesis and is needed by not only animals and other organisms, but also the plants which make it.
Methane is given off by animals as a waste gas.
Oxygen
No. Oxygen is produced as a waste product of photosynthesis and is excreted from the plant as it is not needed by the plant.
Carbon Dioxide Leaves Oxygen
Oxygen is the waste product of plants that animals need in the process of oxidative phosphorilation.
When they take in the Carbon Dioxide they release Oxygen, Oxygen is also a byproduct waste of photosynthesis which plants do use.
Carbon dioxide is a waste product to humans and animals. Trees "breath" carbon dioxide and oxygen is their waste product (during daytime). Animals and humans breath oxygen and breath out carbon dioxide. When our cells circulate, they go through the pulmonary artery to the lungs and collect oxygen. They then go back through the heart and out into the rest of our body. Cells bring oxygen to the parts of our body that need it. Their waste is carbon dioxide which is exhaled.
no... it is the other way around
There are a handful of waste products that are products of a plant's respiration. Oxygen is one such waste product.
Carbon dioxide. Carbon dioxide (CO2) is a waste product produced by animals (including humans of course) during respiration. Plants use this as part of the process of photosynthesis, which in turn creates oxygen (as a waste product).
