With suitable examples explain the energy flow through different trophic levels.
What does each bar in this pyramid represent ?

What does the given ecological pyramid represent ?

What does the base tier of the ecological pyramid represent ?

Discuss the energy flow in a food chain formed of three trophic levels.

What does standing crop of a trophic level represent?

The flow of energy along various trophic levels of an ecosystem is :

At each trophic level the energy value :

What amount of energy reach at the highest trophic level ?

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. How many food chains are present in the food web depicted above?
