Mouth - break down food mechanically and chemically
Salivary Glands - produce saliva that contains enzymes which chemically break down food
Esophagus - move food from mouth to stomach through a process called peristalsis
Stomach - chemically break down food with stomach acid, mechanically break down food with the contracting of stomach muscles
Liver - creates bile that helps with digestion, stores, distributes and breaks down nutrients
Gallbladder - temporarily stores bile and squeezes it into the small intestine to break down fat droplets
Pancreas - produces pancreatic juice that contains digestive enzymes and bicarbonate
Small Intestine - absorbs nutrients from chyme
Large Intestine - absorbs water and dries out food, turning it into waste
Rectum - stores waste before it leaves the body
Anus - an opening where waste exits the body
DDT increases as it moves up a food chain.
<h3>Explain how?</h3>
DDT increases or biomagnifies if we look at a food chain. DDT is fat-soluble, which means animals store it in fatty tissues. It also takes a relatively long amount of time to break down.
Thus, if a predator consumes multiple organisms and each organism has a small amount of DDT, the amount of DDT in the predator is going to be the result of all of those small amounts combined.
