Question

in the videos it said that there would be no more 4 trophic levels in grazing part ,but if grass is eaten by grasshopper, grasshopper is eaten by a frog ,frog is eaten by snake,snake is eaten by a fox ,fox is eaten by a lion and lion could be eaten by a vulture. As a result there are 6 trophic levels. Could u now elaborate me this

Answer 1

On an average only 10 percent of food available to a tropic level is transferred to next tropic level.Since amount of available energy becomes less as we move to higher tropic levels so very little usable energy remains after four tropic levels.

In the situation you mentioned many of the organisms are of thr same tropic level. Grasshoper and frog are part of the same tropic level. So you there will be no more than 5 tropic levels
