Question

Explain the 10% rule and calculate the amount of energy available to Lion in following food chain is plants have 20000 joule of energy available from the sun in the food chain -plant— dear— lion.

Answer 1

according to 10%, only 10% of the energy is transferred from one trophic Level to another trophic level and other 90% is vested in the life processes such as respiration digestion etc.

I have written it by myself please mark it as the brainllist if it will help you please say thanks for this answer too. .

the amount of energy available to lion on each 200 Joule

Answer 2

$\huge \bold \color{green} { \underline{ \underline \red {\mathfrak{required \: answer : }}}}$

$\bold \color{green}{ \underline{ \underline \red{10 \: per \: cent \: law}}}$

According to 10 per cent law only 10 per cent of the energy entering a particular trophic level of organisms is available for transfer to the next higher trophic level..the energy available at each successive trophic level is 10 per cent of the previous level..

the 10 per cent law was given by Raymond Lindeman in the year 1942

i) plants can trap only 1% of the sun's energy falling on them..Now ,1% of 2000J is 200J , so energy have actually 200J of energy available in them as food ( the 10 per cent law does not appu at this stage)

ii) the plants are eaten up by deer. now , according to 10 per cent law, 10%of 200J , that's 20J of energy will be available in the deer as flesh of food.

iii) The deer will transfer 10% of its 20J energy to the lion . Thus , the food energy available to the lion will be 10% of 20J which comes to 2J

the above results can be shown more clearly as follows:-

$sun \: \frac{20000j}{1\% \: absorbed} \: \: plants \: \frac{200j}{10\%of \: 200j} \: deer \: \frac{20j}{10\%of \: 20j} \: lion \: \frac{2j}{}$
