Answer:
Based on the relative volumes of the gases in Earth’s atmosphere, nitrogen is actually more than 3 times more than oxygen. Because the troposphere is the lowest atmosphere layer, it contains 75 percent of the atmosphere’s mass.. From largest to smallest, Earth’s atmosphere composition contains nitrogen, oxygen, argon, CO 2 and trace gases.
Explanation:
Answer:
Internal Temperatures
Similarly, the cardiovascular, integumentary (skin and associated structures), respiratory, and muscular systems work together to help the body maintain a stable internal temperature. If body temperature rises, blood vessels in the skin dilate, allowing more blood to flow near the skin's surface.
OR,
The nervous and endocrine systems exert the ultimate control over homeostasis because they coordinate the functions of the body's systems. Regulation of body temperature, blood pressure, pH, and glucose concentration are four examples of how the body maintains homeostasis.

Answer:
The atmosphere will contain more oxygen, resulting in warmer global temperatures.

I did this on my test
Answer:
Ecological pyramid is a graphical representation showing the biomass or bioproductivity at each trophic level in a given ecosystem.
Limitations
The ecological pyramid does not take into account the same species belonging to more than one trophic level.
Functions. this is the very idea behind differentiation.<span />
