create terrestrial food chain debating for tropic level why do we know find food chain of modern for traffic levels in nature
​

Answer 1

Answer:

A terrestrial food chain depicting for trophic levels is:-

Grass (Producer) - Grasshopper (Primary Consumer, Herbivore) - Frog (Secondary Consumer, Carnivore) - Eagle (Tertiary Consumer, Top Level Carnivore)

We do not find food chains with more than four trophic levels in nature because the more the trophic levels increase, the less would be the energy consumed by the organisms in the higher trophic levels. At each trophic level, a large portion of the energy is utilized for the maintenance of the organisms. So, if the trophic levels are more than four, then the energy available to the final member would be so less that it would be insufficient to sustain the life of the organism. That is why, there are rarely more than five steps (or five trophic levels) in a food chain.
