Answer 1

Here are the answers to your questions:

Question 1: **True**
A prion is indeed an infectious, self-reproducing protein structure.

Question 2: **True**
As one organism eats another, toxins can be bioaccumulated and magnified throughout the food chain.

Question 3: **False**
The problem with DDT is that it does not decompose quickly; instead, it persists in the environment and accumulates in organisms.

Question 4: **True**
The Bald Eagle was indeed put on the endangered species list primarily due to the effects of DDT.

Question 5: **False**
Toxic bacteria can pose significant problems to the native food chain of the Great Lakes and can disrupt ecosystems.

Question 6: **False**
Mad Cow disease (BSE) primarily affects the neurological function of the animal, not the respiratory function.

Question 7: **True**
Cattle being fed a carnivorous diet may have led to prion disease, as they are naturally herbivores.

Question 8: **True**
There were indeed only a small number of reported cases of Mad Cow disease in the United States in 2005.

Question 9: **False**
Oxygen is not directly passed through trophic levels in the same way as energy or nutrients; it is produced by photosynthetic organisms and used by others.

Question 10: **False**
Animals at each trophic level typically need to consume more food than the previous level due to energy loss at each step of the food chain (10% rule).
