Answer:
Photosynthesis- 
Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's metabolic activities. Photosynthesis occurs in the chloroplast of a plant, which contains chlorophyll. In order for photosynthesis to take place, it needs to have water and carbon dioxide, the two very important raw materials necessary for this process. In the presence of carbon dioxide, such cells are able to convert this solar energy into energy-rich organic molecules, such as this energy-rich molecule known as glucose. Oxygen the by product of photosynthesis is inhaled by heterotrophs which aids in cellular respiration and other internal processes and then exhales carbon dioxide. ... In like manner, carbon dioxide passes from blood to the alveoli and exhaled after

Answer:
sensor
Explanation:
Homeostasis refers to the ability of an organism to maintain the internal conditions of the body irrespective of the external conditions.
The homeostasis is maintained by the homeostatic mechanism which involves the 3 components which are the receptor or sensor, the integrating centre and the effector or organ.
In the given question, the peripheral chemoreceptors measures and sense the pH of the blood therefore the peripheral chemoreceptor will be considered as the "sensor component" of the homeostatic mechanism.
Thus, the sensor is the correct answer.
