Which would most likely cause problems with digestion and respiration when consumed in high amounts ?

Hello, this seems like a multiple choice question without the given choices. However, I can still help you and give you an idea that can potentially help you choose the choice. 

Fats can contribute to issues regarding digestion and respiration when consumed too much since it clogs up your arteries. If large amounts of fat is continuously consumed for a lengthy period, then obesity and fatal chronic diseases can be a result. For your question, choose the option with the food that has the fattiest content. 

I hope I was able to help you with your question! :)

It's either -limiting factors or -scarce resources but i'd go with my first answer since the food and water are abundant they really aren't scarce
