NEET BIOLOGY

Detailed explanation-1: -Plants use photosynthesis to capture carbon dioxide and then release half of it into the atmosphere through respiration. Plants also release oxygen into the atmosphere through photosynthesis.

Detailed explanation-2: -Carbon is released back into the atmosphere when organisms die, volcanoes erupt, fires blaze, fossil fuels are burned, and through a variety of other mechanisms.

Detailed explanation-3: -Plants take in CO2 during photosynthesis and give out oxygen into the atmosphere, while animals take in oxygen and breathe out carbon dioxide during respiration. In this way, plants and animals help each other in the exchange of gases in the atmosphere. Was this answer helpful?

Detailed explanation-4: -CO2 is transported in the bloodstream to the lungs where it is ultimately removed from the body through exhalation. CO2 plays various roles in the human body including regulation of blood pH, respiratory drive, and affinity of hemoglobin for oxygen (O2).

Detailed explanation-5: -When we breathe out, we release carbon dioxide into the air which is then used by the plants to make their food and the cycle starts all over again. This system is called the oxygen cycle.
