In the following food chain, vertical arrows indicate the energy lost to the environment and horizontal arrows indicate energy transferred to the next trophic level. Which one of the three vertical arrows (A, C and E) and which one of the two horizontal arrows (B and D) will represent more energy transfer? Give reason for your answer.

Energy transfer from one trophic level to other , in a food chain , is

What amount of energy is lost in transferring food energy from one trophic level to another?

A food chain depicts the flow of energy from one trophic level to another. Which of the following represents the percentage of energy transfer from one trophic level to the next?

In which form is the 10% energy available for transfer from one trophic level to the next in an ecospystem?

Food chains and the energy flow within an ecosystem provide an important understanding of contingencies and mutual dependencies of organisms. The given below flow chart depicts the energy flow within some members of a grassland ecosystem. The grass in the below ecosystem transducer 120,000 J of sunlight and fixes it into 12,000 J of energy. It is established that 90% of the energy of one trophic level is not passed to the next trophic level. Further assume that the energy transferred from one trophic level to the next is equally shared among the different organisms at that trophic level. Based on the above information, indicate the amount of energy that an organism C may have received from an organism from the previous trophic level.

The hanging bob of a simple pendulum is displaced to one extreme position B and then released. It swings towards centre position A and then to the other extreme position C. In which position does the bob have : (i) maximum potential energy ? (ii) maximum kinetic energy ? Give reasons for your answer.
