Answer:
Maintaining Homeostasis. The process in which organ systems work to maintain a stable internal environment is called homeostasis. ... Endocrine system: A high concentration of sugar in the blood triggers secretion of insulin by an endocrine gland called the pancreas.
The normal blood glucose level (tested while fasting) for non-diabetics, should be between 3.9 and 5.5 mmol/L (70 to 100 mg/dL). ...
Blood sugar levels for those without diabetes and who are not fasting should be below 6.9 mmol/L (125 mg/dL).
There are lots of different hormones in the human body that serve lots of different functions, but some are used to maintain homeostasis of various physiological parameters, like blood glucose levels. Blood glucose levels are regulated by two opposing hormones: insulin and glucagon.
Roots don't really produce minerals, they're the "storage facility" of a plant, so your answer is "to produce minerals" : D
Answer:
A forest ecosystem can support a limited number of bears because bears are the supreme predators of their ecosystem and very few animals can hunt bears so nature by supporting a limited number of bear populations supports a balanced number of population of its prey like insects, fishes, deer.
Another reason for the limited population of bear is that bear occupies the highest trophic level in the ecosystem so according to 10% law of energy transfer, it will get very less energy from its food so it needs to eat more.
Therefore the population of bears is limited because the environment can not meet the energy requirement of many bears so a forest ecosystem can support a limited number of bears.
