ok man its not a problem and its simple look first of all the digestion starts in the mouth with chemical and mechanical digestion. Amylase is used to break down starch to glucose and theeth is used to grind and chew food. Food is pushed down the oesophagus through perstalisis then enters the sotmach chemical digestion happens here... Pepsin breaks down the protiens to amino acids and HCl is used to denature the amalyse from the mouth.
I Hope it helps!

nid404:
It's A cuz when sewage enters the river it promotes growth of algae and bacteria feed on them;use up a lot of oxygen. But as u go downstream most of the nutrients in the sewage r either used up or fed upon by bacteria......so the groeth of algae and number of bacteria decrease and this restores the level of oxygen.
Tell me if u didn't get it
