Distance swimming -Kierstyn Bittner

How many calories does the average distance swimmer consume?

• 1000-2000

• 10,000-15,000

• 4000-6000

Answer explanation

4000-6000 CORRECT!!! (Distance swimmers burn a lot of calories so they need to consume a lot of calories to sustain themselves throughout their activity)

1000-2000 (this incorrect because swimmers burn more calories than the average person. This is not enough calories to sustain them.

10,000-15,000 (even though swimmers burn a lot of calories this is too many calories for anyone to eat)

How does the amount of calories consumed by a swimmer affect the ecosystem?

• It takes up more land and leads to more deforestation.

•  It takes up less land and helps the environment 

• It has no effect on the environment

Answer explanation

 It takes up more land and leads to more deforestation. CORRECT!!! (The amount of food swimmers eat to be able to perform is well above what the average person should eat therefore if more people ate like them it would lead to more deforestation)

 It takes up less land and helps the environment (This is incorrect because the amount of calories consumed by distance swimmer is more than the average person)

It has no effect on the environment (This is incorrect because the amount of calories consumed by distance swimmer is more than the average person)

How is the carrying capacity affected by the amount of calories a distance swimmer consumes?

• The carrying capacity is increased.

• The carrying capacity is decreased.

•  The carrying capacity does not change.

Answer explanation

The carrying capacity is decreased. CORRECT!!! (The carrying capacity is decreased because the amount of food swimmers eat is far more than the average person should consume taking over more farm land and cattle, therefore decreasing the carrying capacity.)

 The carrying capacity is increased. (This is incorrect because if everyone ate like swimmers there would not be enough resources to go around therefore we would reach carrying capacity faster)

The carrying capacity does not change. (This is incorrect because if everyone ate like swimmers there would not be enough resources to go around therefore we would reach carrying capacity faster)

If a swimmer ate a primarily plant based diet Vs. a primarily animal based diet which would have a heavier effect on the ecosystem and carrying capacity?

•  Plant based diet.

• The animal based diet.

• does not matter, both are equal.

Answer explanation

The animal based diet. CORRECT!!! (A primarily animal based diet would take over far more land for cattle because the animals being raised would need to eat to also take over more crop land. This would all decrease the carrying capacity.)

Plant based diet. (This is incorrect because even though it would take up more croup land it is still less than the animal based diet)

does not matter, both are equal. (This is incorrect because the animal based diet takes over more land)

How does a distance swimmer swimming in extremely cold water adjust their body to it?

• They slowly ease themselves in by swimming short distances and making there way up.

• They start with long distances then go shorter.

• They don't, they just jump right in.

Answer explanation

They slowly ease themselves in by swimming short distances and making their way up. CORRECT!!! (The swimmers need to slowly adjust their body to keep homeostasis and perform well.)

They don't, they just jump right in. (This is incorrect because they would probably get hypothermia)

 They start with long distances then go shorter.(This is incorrect because they are trying to work up to them)

What system helps the swimmer deliver oxygen and nutrients to the muscles during a long swim?

• Digestive system

• Immune system

• The circulatory system

Answer explanation

The circulatory system CORRECT!!! (The circulatory system delivers oxygen and nutrients through the blood keeping them alive and protecting them from the cold.)

Immune system (This is incorrect because while the immune system has a very important job keeping you healthy it does not deliver oxygen to your lungs)

Digestive system(This incorrect because the digestive system does not deliver oxygen to your lungs) 

What is the respiratory system's job during long cold swims?

• Its job is to provide oxygen to the body and remove carbon dioxide?

•  Its job is to keep you happy.

•  It’s job is to help you see.

Answer explanation

 Its job is to provide oxygen to the body and remove carbon dioxide. CORRECT!!!

( The respiratory system keeps the oxygen flowing in your body breathing and works 

harder during cold swims.)

Its job is to keep you happy.(This is incorrect because while it is nice to be happy your respiratory  system is trying to get oxygen in your lungs.)

Its job is to keep you happy.(This is incorrect because while it is nice to be happy your respiratory  system is trying to get oxygen in your lungs.)

What is the main function of the cardiovascular system in extreme cold conditions?

• To keep your fingers and toes from getting frostbite.

•  To keep your organs alive.

• To keep your hair from falling out.

Answer explanation

To keep your organs alive. CORRECT!!! (When faced with extreme cold conditions the cardiovascular system redirects blood flow to the core to keep your internal organs alive)

To keep your fingers and toes from getting frostbite.(This is incorrect because it is mainly trying to keep your main organs alive.)

 To keep your hair from falling out. (It is trying to keep your main organs alive)
