conditions

13. Respiration and decay -:
•Mechanisms in which animal life and bacteria
consume oxygen and release carbon dioxide

14. Percolation
percolation When water seeps through the soil and ends up
in the water table. It then flows into the
streams, lakes, oceans, and other bodies of
water. The process is then repeated again and
again.
