Please answer this: Process:  - Light energy is absorbed by chlorophyll in a plant - The light energy is used to convert carbon dioxide - The plant uses nutrients in the soil - The plant uses carbon dioxide in the air to produce glucose - The plant uses the glucose to give itself energy - Oxygen is released as a by product.  Perturbation hypothesis: suppose less nutrients from the soil used happens, how will it affect LESS sugar and oxygen being produced.  Does the supposed perturbation have an effect (direct or indirect) on the process?
++++++++
Answer: yes


Please answer this: Process:  - Minerals fill spaces between bits of sediment - The sediments become glued together - The glued together parts become hard like cement - The sediment becomes a big rock - The rocks erode slowly - The rocks come apart - The rocks become smaller rocks - The rocks continue to erode into smaller rocks - The process starts again.  Perturbation hypothesis: suppose change in environment slows erosion happens, how will it affect more rocks erode.  Does the supposed perturbation have an effect (direct or indirect) on the process?
++++++++
Answer: yes


Please answer this: Process:  - Air enters the nose or mouth and travels through the windpipe into the lungs - The lungs have a series of smaller and finer tubes and sacs - Air reaches the smallest and finest air sacs called alveoli - Oxygen travels from the alveoli into the blood - Oxygen-rich blood is carried to the heart - Oxygen-rich blood is pumped throughout the body by the heart - Cells take in the oxygen rich blood and release carbon dioxide rich blood - The carbon dioxide rich blood travels to the lungs - Carbon dioxide travels through the throat and is exhaled.  Perturbation hypothesis: suppose a person breathes very heavily happens, how will it affect a GREATER amount of oxygen being delivered to the blood stream.  Does the supposed perturbation have an effect (direct or indirect) on the process?
