Describe feeding relationships and energy flow, and use them to identify trophic levels and navigate food webs
With the help of a diagram, represent the energy flow through different trophic level.
In the trophic structure, autotrophs are living organisms that:
Are at the top of the chain, referred to as tertiary producers.
Photosynthetic organisms that produce their own energy
Organisms that receive their energy by consuming producers such as plants
Help to decompose the remains of dead organisms
