Question

_____________maintains balance of oxygen and carbon dioxide concentration in the atmosphere.​

Answer 1

Answer:

Plant

Explanation

The balance of oxygen and carbondioxide is maintained in the atmosphere by the oxygen released by plants during photosynthesis and carbondioxide released by human,animals etc. ... The balance of oxygen and carbondioxide is made due to respreration and photosinthesis

Answer 2

Answer:

The percentage of oxygen in our atmosphere has remained almost constant for thousands of years. This is due to three important processes that occur simultaneously and balance out any changes.

Respiration – nearly all living cells use oxygen to obtain energy from their food using respiration. This process takes in oxygen from the atmosphere and releases carbon dioxide.

Combustion – whenever organic material, such as wood or grass, burns, oxygen reacts with the carbon and hydrogen in the material, releasing heat and light in the form of fire. This process takes in oxygen from the atmosphere and releases carbon dioxide.

Photosynthesis – plants produce their own food in the form of glucose using the process of photosynthesis. This process uses sunlight (and so only occurs during the day) to remove carbon dioxide from the atmosphere and release oxygen.

In the last few thousand years, these three processes have balanced each other out, maintaining levels of oxygen at around 21 per cent.
