Every step of energy transformation have loss. Progress through the energy chain, the amount of energy transferred would unavoidably degraded. So as the chain progress it get narrower to a pyramid shape.
because only 10% of the energy from one organism is passed to the next
Because less energy is avaible to organisms XP
it can be A)The ecosystem will not be able to support as many tertiary consumers. B)It will decrease the amount of energy transferred to higher trophic levels. C)The ecosystem will be able to support more organisms at higher trophic levels.Eliminate D)The ecosystem will become stagnant due to excess producers and organisms in higher trophic levels will die out.
Due to poor trophic transfer efficiency, most energy is lost at higher trophic levels.
Only about ten percent of energy is transferred from one trophic level to the next in an ecosystem. This is why the amount of animals in higher levels is smaller.
The most accurate method is to use a pyramid of energy to show the transfer of energy between trophic levels
This is because only about 10% of energy is transferred from one trophic level to the next. The other 90% or so is used up by the organism itself for life processes, digestion, excretion, growth, movement and transpiration for plants. Therefore the amount of energy decrease up the trophic levels and the higher the trophic level, the less the energy received.
As you climb trophic levels the general amount of energy lost is 90% so you get about 1/10 of the energy that was consumed by the animal per trophic level.

9o% of energy is lost at each level
The number is limited by the amount of energy lost at each trophic level. Most cannot exceed 5.

Energy and biomass decrease as the trophic levels increase.The general rule is that only about 10% of the total energy consumed from the previous trophic level will be passed onto the next level as useable energy. As a result it takes a large biomass of producers (plants) to support the total biomass of primary consumers. The primary consumers use the energy they obtain from the plants to maintain body temperature and move or it is lost as waste. Most energy is considered to be lost as heat. This pattern is repeated for secondary consumers and so on. (This is a generality; the amount of energy transferred changes in real situations.)All life is directly related to the original energy source, in most cases the sun. The higher up you go in the trophic level, the less life (overall biomass) that can be supported by the original energy source due to the loss of energy in each level.

Trophic levels are the positions of organisms in a food chain. Energy is transferred through the trophic levels through ingestion at each level.
