The correct answer is C. A decrease in the population of sea ducks
Explanation:
Food webs are diagrams that represent the relationship of organisms in an ecosystem by showing feeding or predatory relationships. This means food webs show which organisms eats another organism. In the case of the food web presented, this shows bald eagles fed on sea ducks and large piscivorous fish, this implies for survival bald eagles need from these two organisms. In this context, a decrease in the population of sea ducks (option C) would cause a decrease in the population of eagles because fewer sea ducks imply less food for eagles, and therefore fewer resources to survive.
The reason as to why fungi fossils seem so rare is that they are usually microscopic and often difficult or impossible to identify.
Not much information on fungi fossils has been documented. This could be because fungi fruiting bodies consist of soft, fleshy and easily degradable tissues which due to their poor integrity do not keep or preserve as well as animal tissue.
Even when available, it takes a trained eye to recognize fungal fossils. Not many people have the training and expertise to recognize the fossils.

Air that enters the pleural space during inspiration but is unable to exit during expiration creates a condition called Pneumothorax.
<h3>What is Pneumothorax?</h3>
An abnormal buildup of air in the pleural space between the lung and the chest wall is known as a pneumothorax. Shortness of breath and quick, acute, one-sided chest discomfort are common symptoms . A tension pneumothorax happens when an area of injured tissue forms a one-way valve, increasing the amount of air in the gap between the chest wall and the lungs. As a result, there may be an oxygen deficiency that worsens with time and low blood pressure. Obstructive shock is a type of shock that results from this and can be lethal if left untreated. A pneumothorax can very infrequently affect both lungs. Although the term "collapsed lung" can also refer to atelectasis, it is frequently used to describe it.
