So, as a result of warming in the Sea of ​​Japan, spawning navaga shifted to an earlier date, because of the reduction of the area of ​​"cold spots" in the eastern Bering Sea shelf feeding migration of pollock, halibut and crab are lengthened, but because of the temperature rise to the east of Japan, spawning saury expanding.

How maintaining homeostasis gives us greater freedom of activity from dependence upon changes in the external environment?
kotykmax [81]

Homeostasis is the ability of an organism to stabilise its internal body metabolism in response to changes in the external environment. The ability to carry out homeostasis provides an organism a lot of freedom from the dependence on the external environment. For example, reptiles are cold blooded animals. They require the heat of the sun for body metabolism. But in the absence of heat or in case of harsh winters, the reptiles will not be able to adjust to the temperature and as a result perish. Mammals are warm-blooded animals, being able to regulate their internal body temperature as and when necessary. Winters will affect the warm-blooded animals less because their body will increase in metabolism in response to cold temperatures to raise the internal body temperature. This is possible only through homeostasis.
