Interdependence is a relationship between one living thing and another and between biotic and abiotic components that need one another. In plants through the process of photosynthesis, make food for cell energy. The materials plants use for photosynthesis are air and carbon dioxide to produce glucose and oxygen. Plants can obtain carbon dioxide from the results of animal respiration. Apart from this another contributing relationship i.e., plants can also obtain nutrients by absorbing nutrients from decaying animals. Plants also need the help of animals to help the pollination process.
