Whales play an important part within the marine ecosystem, and if they were to disappear, the delicate balance of nature would be disrupted. According to Scitable, every time a whale dies, it leaves behind a carcass that provides food and vital nutrition for literally hundreds of marine life organisms. For instance, species of scavenger crustaceans and worms feast upon whale carcasses for sustenance.
Other species of fish, including sharks, also obtain food from a whale carcass. Without this bountiful source of food, certain parts of the ocean would cease to thrive.
Living whales also heavily contribute to the marine ecosystem in the form of whale feces. According to the Columbia Basin Fish and Wildlife News, a study found that whale feces is filled with rich nutrients that include nitrogen, which stimulates the growth of plants. Organisms, such as plankton, that feed the ocean food chain also benefit from tons of whale feces floating on the ocean's surface. The disappearance of this source of natural nitrogen is likely to have a negative effect on plant and food production.
An overpopulation of sea lions would quickly be evident as soon as the whales that prey on them vanished. Likewise, the economies of Canada and the United States would suffer from a lack of tourist dollars because whale watching is very popular.
Cholecystitis is a condition caused by inflammation of the gallbladder. The gallbladder collects and stores bile from the liver, and releases it when you eat. It is needed because the liver produce bile constantly. When the gallbladder becomes inflamed, it causes right upper abdominal pain with nausea, vomiting, and fever. Changing diet patterns is important part of the treatment since the gallbladder’s function is reliant on food. You have to lose weight and have to do it slowly, so you have to reduce calorie intake (just eat less). Another important thing is reducing fat and increasing intake of fiber, so the gallbladder does not have to work hard secreting bile to digest fats in food, which reduces inflammation.

Explanation:
Context clues: Context clues can simply be defined as the hints that we get about the meaning of a word by reading a sentence or sentences related to that word. We can simply infer the meaning of the word by reading the sentence.
Tone: The tone of a sentence helps us to identify what the word in the sentence might mean. For example, if a sentence has a happy tone, we might infer that the word is related to some kind of happy meaning.
Word choice: The word choice refers to the selection of words by the writer. The usage of words by the writer helps us determine what the writer might mean by a word.
