Answer:
0.1% of energy
Explanation:
Energy flow: From the whole quantity of energy that reaches the earth's surface, autotroph organisms or producers absorb only 0.1 or 1%.
From the input of solar energy begins a unidirectional energy flow through all the organisms in the ecosystem, from autotrophs to heterotrophs, until it is dissipated in the environment.
At each trophic level occurs an energy transfer to the next, with only 10% being usable in each of them. This assessment is called "The 10% rule". As a general rule, only about 10% of the energy stored as biomass at one trophic level, per unit time, ends up as biomass at the next trophic level, in the same unit of time.
If wheat transferred 10% of the energy to mice, and of that 10% mice transferred 10% of the energy to hawk, then the percentage of energy transferred from the first trophic level to the third equals 0.1%.
10% (1st TL-2nd TL) / 10% (2nd TL - 3rd TL) = 0.1% (1stTL - 3rd TL)
<em>TL = Trophic level </em>
Answer:
3) B
4) A
5) B
Explanation:
3) Sun heats up the air of a particular region due to which the air heated rises up ( as hot air is lighter than cool air ). When the hot sir rises , the cool air from other region comes there & like this wind blow.
4) A toaster uses electricity to produce heat in order to toast bread So here the electric energy is converted to thermal energy.
5) Windmills , Hydroelectricity dams & Ethanol plants have turbines & turbines do have a generator which is to be rotated . When the generator is rotated , electricity is generated.
Answer:
by measuring and examining a random sample of the population being analyzed.
