उत्तर
The ecosystem in which we live, all organisms are interdependent on each other. In this cycle of interdependence, carbon dioxide is produced by animals. During photosynthesis plants intake carbon dioxide and give us oxygen (which many other organisms require for respiration). In the absence of carbon dioxide plants will not be able to perform photosynthesis and will die eventually, also organisms which depend on plants for food will be left with no food at all and it will disturb the carbon dioxide – oxygen ratio. If there is no carbon dioxide, oxygen level will decrease simultaneously and we know there is no life without oxygen on earth.
