Question

question 21 2.5 points consider the following processes: respiration, combustion, polymerization, nitrification, industrial fixation of nitrogen, and photosynthesis. how many of these result in the release of oxygen into the atmosphere? none 1 2 4 all

Explanation:

Step1: Analyze respiration

Respiration consumes oxygen and releases carbon - dioxide.

Step2: Analyze combustion

Combustion consumes oxygen and releases carbon - dioxide and other products.

Step3: Analyze polymerization

Polymerization reactions do not typically release oxygen into the atmosphere.

Step4: Analyze nitrification

Nitrification is a process in the nitrogen cycle and does not release oxygen into the atmosphere.

Step5: Analyze industrial fixation of nitrogen

Industrial nitrogen fixation does not release oxygen into the atmosphere.

Step6: Analyze photosynthesis

Photosynthesis uses carbon - dioxide and water to produce glucose and releases oxygen into the atmosphere.
