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.
Decrease in higher levels.
3 (apex)
four
A food web connects numbers of food chains together. When one tropic level loses a predator, over time another takes its place.
Yes, if you mean in terms of food chains and trophic levels, etc.
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.
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.
Yes, organisms at higher trophic levels tend to have fewer individuals compared to those at lower trophic levels. This is because energy is lost as it is transferred up the food chain, resulting in a pyramid-shaped distribution of biomass and population numbers.
Yes, very definitely. There are even levels in the ocean in which certain fish swim or live.
During the progression of each stage, the organisms in the food chain exert tons of energy. Most chains are broken down to four stages for that reason.
