In a food chain 200 kg of wheat is fed on by 18 kg of mice which in turn are eaten by 1kg of hawk. What is the percentage energy
Nikolay [14]

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>

Light energy from the sun is the primary source for all living organisms. So how does the sun provide energy for all living orga
Vera_Pavlovna [14]

Answer: Heat or thermal energy coming from the sun provides energy for living organisms through heat transfer. For plants light energy is absorbed by the leaves and enters the stomata which activates the thylakoids and releases amount of electrons for chemical reactions. Through light energy plants produces glucose and releases oxygen gas as a by-product of the reaction. For this process energy is formed (ATP)
