Most animals give off carbon dioxide as a waste product for life. This is called "aerobic".
Methane is given off by animals as a waste gas.
The waste gas given off by animals is methane gas (CH4). It is often produced as a product of the bacteria in the digestive system or gut of many animals, such as ruminate animals like cows.
Oxygen is given off as a waste product.
Carbon Dioxide. Animals breath this out as a waste product of respiration. Plants take this in as a material to use in photosynthesis.
From the atmosphere, and also as a waste product exhaled by animals during respiration. The Earth's atmosphere consists of 0.04% Carbon Dioxide, and it is exhaled by all mammals as a waste product. Animals and plants need each other, as what is waste gas to the one, is essential for the other to live.
Carbon dioxide (CO2) is the waste gas.
Carbon dioxide .
Plants use carbon dioxide and give off oxygen as a waste product.
The gas given off as a waste product in cellular respiration is carbon dioxide. Lactic acid is also produced during this.
The gas that is excreted as a waste product of autotrophic nutrition in maple trees is oxygen. It is produced in the light stage of photosynthesis.
CO2 AKA carbon dioxide.
The gas given off as a waste product of photosynthesis is oxygen. Glucose is also made during photosynthesis. These products are made from carbon dioxide and water.
Depends on what reaction you're considering. For plants Oxygen is a waste gas, for animals its CO2, in an oil well it might be methane.
The waste product of nuclear fusion is helium, an inert gas and not radioactive. The waste products of nuclear fission reactions are radioactive.
