They do not affect the other species nearby them and because of these reasons they cannot be considered as ecological community.
ANSWER: A. Exercise is important for the body to function properly.
Exercise deliver adequate amounts of oxygen and remove waste from body tissues by regulating nervous, respiratory, circulatory and hormonal systems in the body. During exercise, body tissues and other metabolic processes in the body requires oxygen.Low levels of oxygen and higher levels of carbon dioxides are mainly detected by sympathetic division of the autonomic nervous system which control the physical activity of the body by increasing heart rate, blood pressure and respiration as a result of this there is an increase in the amount of blood pumped per minute by the heart and oxygenated body gets distributed to the tissues. This also involves release of glucose by the liver as an energy reservoir to control the level of blood glucose pancreas secrete insulin hormone , thyroid gland is also stimulated in response to increase heart rate.
Answer:
an increase in water pollution
excessive rain
When our body requires to more energy in the absence of oxygen it performs anaerobic respiration.
In the absence of oxygen the terminal electron acceptor , pyruvate produced form glycolysis undergoes anaerobic respiration to produce lactic acid and replenish the NADH required for glycolysis for producing more ATP.
