Answer:
Atmosphere 
Explanation:
Phosphorus cycle in nature is a unique cycle compared to the other natural biological and chemical cycles such as the carbon, nitrogen, sulfur and water cycles, as there is no gaseous phase in the phosphorous cycle. Due to the prevailing atmospheric temperature and pressure which are not appropriate for the formation of gases associated with phosphorus, the compounds in nature where phosphorus can be found are not gases. Phosphorus can therefore be found majorly in sedimentary rocks.
 
        
             
        
        
        
Two wet glass slides stick together because the adhesive force acting between the glass and water is responsible for sticking up of the slides , the water trapped between the slides has a lower pressure as compared to the atmospheric pressures
        
             
        
        
        
Both plants and animals are able to do cellular respiration. Plants convert nutrients from the soil into usable energy. 
This is the plant cellular respiration formula:
oxygen + glucose -> carbon dioxide + water + heat energy
Hope this helped! Let me know if there is anything I need to clarify or explain more in depth
