Pituitary gland.
When you feel stress, the pituitary gland, at the base of the brain, increases its production of the hormone ACTH. This hormone tells the adrenal glands, found at the top of your kidneys, to increase their production of hormones. These stress hormones help you to concentrate, speed your reaction time, and boost your strength. Your hypothalamus also helps your body respond to stress.

Answer:
Plant to animal to atmosphere.
Explanation:
- The carbon cycle describes the recycling of carbon from and back to the atmosphere.
- Plants utilize the carbondioxide present in the atmosphere to produce carbohydrates in the presence of light through the process of photosynthesis.
- When plants are consumed by animals, the carbon becomes a part of the animal.
- Animals break down glucose molecules into energy (ATP), releasing water and carbondioxide in a process called cellular respiration.
- This carbondioxide, as it is useless for animal cells, is released back into the atmosphere through gaseous exchange in the lungs.
