Answer:
True
Step-by-step explanation:
The gases such as nitrogen, carbon, oxygen are present in a certain amount in the atmosphere. This amount is always constant due to the gaseous cycle in our ecosystem. The gaseous cycle is coming under the biogeochemical cycle. Unlike energy and water, these gases go to the atmosphere and then come to the biosphere in a cyclic manner. This gaseous cycle includes the nitrogen cycle, oxygen cycle, and carbon dioxide cycle. This gaseous cycle justifies the given statement.
