Why do plants and animals release carbon dioxide?

Answer 1

Cells produce carbon dioxide as a result from making energy, and when they do this they also produce small amounts of H2o which you then breath out.

^^^I just seen this answer and decided to point out to anyone who believes this answer. Do we really breath out water? I'm guessing they mean CO2 but not sure.

Answer 2

As a By product of Respiration / metabolism CO2 is produced. thus when the oxygenated blood reaches the cell. gas exchange occurs with the O2 entering the cell and CO2 leaving. the CO2 is then carried to the right side of the heart for respiration to eventually occur in the lungs and get rid of the excess CO2

Answer 3

This process is known as respiration. Living cells take in oxygen and react it with glucose, a process which creates energy for the organism to live off.

The products of this reaction are carbon dioxide and water.

Answer 4

Actually, plants take carbon dioxide and give offoxygen. This happens through a process called 'photosynthesis.' Photosynthesis is an endothermic reaction which requires an input of energy (meaning it can't happen on it's own). Plants get the energy to power this process from the sun.

Using carbon dioxide and water, plants rearrange the molecules to form oxygen gas and glucose, or sugar, which they use for energy. The chemical reaction is given by the following formula:

6 CO2 + 6 H2O => C6H12O6 + 6 O2

Answer 5

cellular respiration. its not only done in your lungs, every cell does it. its part of how you make energy. the most common way this is done is through the krebs cycle. you take glucose, and split it through glycolosis to make 2 atp (also produces 2 NADH and 2 pyruvates). the pyruvate can then go through fermentation not using oxygen or kreb cycle which produces more energy (32-36 more atp) using oxygen and forming CO2 and water.

Answer 6

Plants release carbon dioxide during respiration, a process that converts organic compounds into energy. Animals release carbon dioxide as a byproduct of cellular respiration, where they break down food to generate energy. Both plants and animals play a role in the carbon cycle by releasing carbon dioxide back into the atmosphere.

Answer 7

Animals breathe in oxygen and release carbon dioxide.

Plants absorb carbon dioxide and release oxygen.

Answer 8

During cellular respiration the oxidation of respiratory material (organic compounds) takes place in mitochondrion hence CO2 is released as a result of aerobic respiration.

Answer 9

Cellular Respiration.
