In the following food chain, 100 J of energy is available to the lion. How much energy was available to the producer?
Plants `to` Deer `to ` Lion

In the following food chain, 20,000 J of energy was available to the plants. How much energy would be available to man in this chain ? Plants to Sheep to Man

In the following food chain, plants provide 500 J of energy to rats. How much energy will be available to hawks from snakes ? Plants to Rats Snakes to Hawks

(a) Explain why, a food chain usually cannot have more than three of four steps. (b) Calculate the amount of energy that will be available to big fish in the following food chain, if 10,000 J of energy is available to small algae from the sun : Small algae to Zooplankton to Fish to Big fish

Calculate the amount of energy available to lion in the following food chain if plants have 20000 J of energy available from the sun: Plants to Deer to Lion

(a) How is energy introduced into the ecosystem ? (b) Consider the following food chains : (i) Plants to Mice to Snakes to Hawks (ii) Plants to Mice to Hawks If energy available at the producer level in both the food chains is 100 J, in which case will hawks get more energy as food and by how much ? Justify your answer.

Consider the following food chain : Grass to Mice to Snakes to Peacocks If in this chain, 100 J of energy is available at the producer level, then calculate the energy transferred to the peacocks as food. State the law used in the calculations.

During food chain, the maximum energy is stored in:

Which energy is freely available in ample amount ?
