The organisms that create all the usable food energy on Earth are called the producers. These organisms are able to produce food through the different resources such as the energy from the Sun, the carbon dioxide, and water and minerals that they absorb from the soil
When people speak about convection, they are usually referring to the uneven heating that occurs on the surface of the earth.
Consequences of an inconsistent heating system:
Because of the disparity in temperature distribution, certain areas of the environment are hotter than others, and there are also shifts in volume and tension as a result.
It generates updrafts, which in turn may lead to thunderstorms and other types of severe weather.
The Earth has moved slightly on its axis.
Because the sun's rays are directed directly at the equator, the temperature there is higher than in other parts of the planet.
As you approach farther north or further south of the equator, they drop down in an incline or at an angle.
Because of this, the temperature of the earth is uneven, which in turn shapes the wind and the flow of the sea and makes it possible for life to exist.

As the bear enters hibernation, its metabolic processes such as body temperature, heart rate, and respiratory rate are reduced. But bears do not lower the body temperature as much as once thought. Their hibernation temperature is around 88 degrees and waking temperature is 100 degrees F. This relatively high sleeping temperature allows bears to become fully alert if aroused, perhaps to enable the bear to protect itself from predators and other dangers without unnecessarily taxing their energy reserves. Over the course of a hibernating season it is thought that bears use approximately 4 thousand calories a day, which results in a weight loss of about 20 percent of it body weight by spring.
In contrast to compact bone, spongy bones does not contain true Haversian systems( tiny tubes that form a network in bone and contain blood vessels) but consist of an irregular lattice of thin plates of bone called trabeculae.The spaces between trabeculae are filled with marrow. The cells of the red marrow are responsible for producing blood. Within trabeculae lie lacunae which contain osteocytes.<span> Blood vessels from the periosteum penetrate through to the spongy bone, and osteocytes in the trabeculae are nourished directly from the blood circulating through the marrow cavities.</span>
