I think it A because Cyanobacteria absorb co2 from the atmosphere and then release oxygen To the atmosphere
Answer:
Homeostasis is defined as the state of body in which body maintains several chemical and physical changes inside the body affected by external factors.
Negative feedback loop includes a sensor, stimulus, control center, and effector which is used to control homeostasis.
A negative feedback loop is a reaction that reduce an excessive response and maintain the functions within the normal range. for example: if temperature and blood glucose level increases in the body, negative feedback loops control both the variables and maintain homeostasis.
Hence, negative feedback loops used to control body homeostasis.
A dependent variable is a value that depends on another, so what relies on the other! :)
They react to external factors like light, temperature etc
