Answer:
Negative feedback.
Explanation:
The normal carbon dioxide levels after resting, the breathing rate also decreases which is an example of negative feedback because the body moves towards stability or equilibrium conditions. There is a direct relationship between breathing rate and carbondioxide levels means if one is increases the other automatically increases in order to maintain homeostasis in the body so we can say that this relationship is very important to maintain .stability in the body
Intestinal gland secretes intestinal juice ,it contains enzymes and their role is to decompose food more and then conduct them into the large intestine or by intestinal absorption to the blood
According to the research, the correct option is photosynthesis. The process of <u>photosynthesis</u> generates the oxygen that we breathe and the food that we eat.
<h3>What is photosynthesis?</h3>
It is the process of obtaining energy from plants, algae and certain bacteria to synthesize organic substances from other inorganic ones.
This metabolic process carried out by some cells of autotrophic organisms is essential for life since, starting from light and inorganic matter, it manages to synthesize organic matter and allows carbon dioxide (CO2) to be fixed from the atmosphere and oxygen to be released.
Therefore, we can conclude that according to the research, the correct option is photosynthesis. The process of <u>photosynthesis</u> generates the oxygen that we breathe and the food that we eat.
