Cutting down trees in the forest to make furniture because trees produce oxygen
Cellular respiration is the term given to the metabolic reactions responsible for the conversion of biochemical energy in nutrients to adenosine triphosphate (ATP) with the generation of waste productions. ATP is required to provide the chemical energy to reactions in the cell that maintain homeostasis.
Through the process of global warming
Carbon dioxide is converted into sugars in a process called carbon fixation; photosynthesis captures energy from sunlight to convert carbon dioxide into carbohydrate. ... These nutrients are oxidized to produce carbon dioxide and water, and to release chemical energy to drive the organism's metabolism.
