Lets, start with,
What is the Food Chain?
A food chain is a network of links in a food web. Here, the producers are consumed by the predators-primary and secondary consumers and then the detritivores and finally by decomposers. When many such individual food chains occur in an ecosystem, it is known as Food Web.

A food chain shows a direct transfer of energy between organisms. As every organism can feed on multiple things, a food web is a much more realistic and simplified method of transferring energy in an ecosystem.

What is Food Web?
There are unique interactions and relationships which are involved in the transportation of energy. The energy, once produced and captured, is distributed throughout the various living organisms. This transfer of energy is termed as the food web.

Trophic level
The producers and consumers in the ecosystem can be arranged into different feeding groups and are known as trophic levels or the feeding level.

- The producers (plants) represent the first trophic level.
- Herbivores (primary consumers) present the second trophic level.
- Primary carnivores (secondary consumers) represent the third trophic level
- Top carnivores (tertiary consumers) represent the last level.

All the above-mentioned topics are described in an interactive and efficient manner so that the students could easily understand them.
