Oxygen and Carbon Dioxide

The video explains how different organisms respire in various environments. Land plants and animals use oxygen from the air, while aquatic organisms use dissolved oxygen. Soil organisms utilize trapped air in the soil. The balance of oxygen and carbon dioxide is maintained through respiration and photosynthesis, highlighting the interdependence of plants and animals.
