Nutrients are brought to spongy bone through which mechanism? (2 points)
Kisachek [45]

Nutrients are brought to spongy bone by diffusion through canaliculi

<h3>How is bone tissue nourished?</h3>

Nutrition is provided by the so-called Nourishing Foramina, which are openings in the bone through which blood vessels, veins and arteries pass. Also with regard to nutrition, Volkmann's canals provide the main entry route for vessels to cross compact bone.

With this information, we can conclude that Volkmann canals also contain nutritional vessels arising from the periosteal and endosteal bone surface.

To overcome the problem of oxygen debt, a person should take rest that allows the body to replenish its oxygen supply.

How much chemical energy (stored as biomass) is available to primary consumers from 10,000 kcal of primary productivity?
atroni [7]
The answer is “d” (1,000 kcal). As the trophic level increases energy is decreases by 10 times that of the previous level. If a system has 10,000 kcal, then the primary consumer have 10 times less (10,000/10) which is 1,000 kcal. The secondary consumers have 100 kcal and the tertiary have 10 kcal. Only 10% of the energy at each trophic level goes on to the next.
