Please rephrase your question. I fail to understand what you wish to know.
Trophic levels and food chains are connected in number of ways. Trophic levels show the energy transfer throughout the species in different food chains.
A group of organisms that occupy the same position in a food chain.
Food chains demonstrate the feeding patterns between orgainisms in a specific ecosystem and food webs include multiple food chains and show how they are interconnected by the species and ecosystems within it.

Yes, if you mean in terms of food chains and trophic levels, etc.
Trophic levels play a significant role in the transfer of energy within food chains and food webs. Each organism has a position n the trophic level and energy is transferred through succession.
A food web connects numbers of food chains together. When one tropic level loses a predator, over time another takes its place.
Each tropic level is only able to use about 10% of the energy from its food. Because of this energy loss, there is usually not enough energy left to after a fourth tropic level to support anything higher.
food chains that overlap I think are called overlapping food chains. Food chains that overlap are called overlapping food chains.
