A food handler who fails to report illness to the person in charge could cause a physical contamination?
Hunter-Best [27]

Answer:

True

Explanation:

Physical contamination are foreign objects such as hair, fingernails, broken glasses , jewelries etc that are mixed with food. Although, it is important for a food handler who realizes that he is sick such as having fever, jaundice,wound while working to report such to his supervisor or manager,who will then take necessary action and to avoid risk of contamination; yet not the only cause of physical food contamination.

Physical contamination does not necessarily have to occur until the food handler is sick. It could be as a result of carelessness or not paying attention enough by the food handler . Physical contamination might not at all times cause injury or illness to the customer, yet such could bring discomfort to a customer who notices foreign objects in his food while eating. To avoid risk of physical food contamination, it is important for food handlers to keep jewelries to a minimum, wash fruits and vegetables thoroughly, wear hear neatly tied back, throw out and replace cracked, chipped, or broken dishware, glassware and equipment amongst others.

Why are human populations not limited by the carrying capacity of their ecosystems
Akimi4 [234]

The human populations are not limited by the carrying capacity of their ecosystems, and they are the only species on Earth that are able to perform such a thing. The main reason for this is that the humans are able to transport resources of all sorts and for all needs from very distant places. Even if there's a very large population surrounded by desert, the humans are still able to survive by simply bringing in the necessary things from other places throughout he means of transportation. Another reason is that the humans are able to change and manipulate their environment to certain extent, being able to provide for themselves even in ecosystems that naturally are nowhere near close to provide those things for them.
