Answer;
The above statement is false
The total number of organisms an ecosystem can support is its carrying capacity.
Explanation;
-Carrying capacity is the average population density or population size of a species below which its numbers tend to increase and above which its numbers tend to decrease because of shortages of resources.
-For a given region, carrying capacity is the maximum number of individuals of a given species that an area's resources can sustain indefinitely without significantly depleting or degrading those resources.
The carrying capacity is different for each species. in a habitat because of that species’ particular food, shelter, and social requirements.

Osteoporosis refers to a condition that weakens the bone, and enhances the threat of unanticipated and sudden fractures, also known as porous bones. It leads to an enhanced loss of bone mass and strength. The disease often advances without any kind of pain or signs.
There is a direct association between the reduction of estrogen post menopause and the emergence of osteoporosis. Postmenopause, the breakdown or resorption of bone takes over the formation of novel bone. Estrogen diminishes the function and number of osteoclasts. Thus, the reduction in the levels of estrogen after menopause leads to bone loss.
It is a cold Artic air mass over Siberia. Air masses are altered because it doesn't stay in one place and changes as it moves due to the temperature of environment that can be caused by moisture. The cold Artic Mass from Siberia will go to the North Pole, Canada then moves further to the South area.
