Answer:T= 2898*10^-5K
Explanation:
wavelength = 10cm
Using Wien's Law
maximum wavelength= 2898*10^-6/temp(K)
thus T=2898*10^-6/10*10^-2
T= 2898*10^-5K
this is the maximum observed temperature of 10 cm wavelength black body
since this temperature is close to the diurnal equilibrium temperature, that's why it not get much colder.
<u>Answer:</u>
<em>Energy is left behind the food chain starting with one trophic level then onto the next. </em>
In any case, just around 10 percent of the complete energy put away in living beings at one trophic level is really moved to <em>living beings at the following trophic level. </em>
The remainder of the energy is utilized for metabolic procedures or lost to nature as warmth. Energy that isn't utilized in a <em>biological system</em> is in the end lost as warmth.
<em>Energy and supplements are gone around through the food chain, when one creature eats another life form.</em>
