If the energy available at tertiary consumer level is 20J in a food chain, how much energy will be available at the primary consumer level ? (10% law)

For a reversible reaction, A hArr B , which one of the following statements is wrong from given energy profile diagram ?

Following criteria should be taken in consideration for resonance. The major contributor is the one with the lower energy. Good contributors generally have all octets satisfied, as many bonds as possible and as little charge separation as possible. Negative charges are more stable on the more electronegative atoms. Resonance stabilization is most important when it serves to delocalize a charge over two or more atoms Observe the following structures H_(2)C=""^(+)underset(I)(N)H_(2) harr""^(+) underset(II)(CH_(2))-NH_(2)

Study the following statements concerning food chains and select the correct ones. (i) Removal of 80% of tigers from an area resulted in greatly increased growth of vegetation. (ii) Removal of most of the carnivores resulted in an increased population of deer. (iii)The length of food chains is generally limited to 3-4 trophic levels due to energy loss. (iv) The length of food chains may vary from 2 to 8 trophic levels.

Suppose India had a target of producing by 2020 AD, 200,000 MW of electric power, ten percent of which was to be obtained from nuclear power plants. Suppose we are given that, on an average, the efficiency of utilization (i.e. conversion to electric energy) of thermal energy produced in a reactor was 25%. How much amount of fissionable uranium would our country need per year by 2020? Take the heat energy per fission of 235U to be about 200MeV.
