|
|
Animals produce oxygen that plants turn into carbon dioxide.
|
Detailed explanation-1: -1. Animals breathe oxygen and exhale carbon dioxide. Plants take in carbon dioxide and release oxygen back into the air.
Detailed explanation-2: -Animals, during respiration, take in oxygen and release carbon dioxide gas. Plants, on the other hand, utilize this carbon dioxide gas in the process of photosynthesis to produce food and release oxygen in the atmosphere. Thus, we can say that plants and animals help each other in exchange of gases in the atmosphere.
Detailed explanation-3: -The correct option is C) Plants produce O2 and sugars and animals produce CO2 and H2 O. This statement best describe the relationship between plant and animals on earth as plant are autotrophs and they can produce sugar and oxygen with the help of carbon dioxide and water molecule in presence of sunlight.
Detailed explanation-4: -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.
Detailed explanation-5: -Together, respiration and photosynthesis make a cycle of life. Energy from the sun is captured in material by plants, which animals eat and expel as waste, that plants can recycle to capture more energy. The cycle emphasizes how important oxygen is to living things in general.
