Answer:  Limitation of energy

Explanation:

The energy is very limited as soon as it reaches the higher tropic level. The energy is highest at the basic level which meas at the producers.

As we move up to the next tropic levels only 10 of the energy is transferred to another level.

So, as we move up the energy keeps on decreasing so there is only 4 or 5 tropic level. Loss of energy in the form of heat and less transfer to another level limits the number of trophic level.

Answer:

According to the 10% law, only 10% of energy will be gained by the individuals who are present at a higher trophic levels by eating the organism present at their lower trophic level.  

So there would be very little energy available for the organism present at 3rd or 4th trophic level therefore tropic level is limited. This is the reason why a low number of organisms are present at higher tropic levels than lower trophic level.

Therefore decrease in the energy availability at the higher trophic level limits the number of trophic levels in a food chain of the web.

yuradex [85]

Answer:

Energy decreases as it moves up trophic levels because energy is lost as metabolic heat when the organisms from one trophic level are consumed by organisms from the next level. Trophic level transfer efficiency (TLTE) measures the amount of energy that is transferred between trophic levels.

ozzi
Prokaryotes and eukaryotes both have a plasma membrane, mitochondria, golgi apparatus, and endoplasmic reticulum in common. But, prokaryotes have cell walls, chloroplast, and larger vacuoles because they are plant cells and animals don't need chloroplast since they don't undergo photosynthesis and don't need to hold as much water in their vacuoles.

Vsevolod [243]
In the process of the nitrogen cycle. <span>               
The nitrogen cycle is a biogeochemical succession process of nitrogen that involves: fixation, ammonification, nitrification, and denitrification. Like any other biogeochemical cycles. This process undergoes and affects the biological, geometrical and chemical aspects in the ecosystem and the abiotic and biotic community. Hence, the nitrogen cycle leads the abiotic component –nitrogen- to contribute to the biotic community, decomposition and primal production. Further, it becomes an essential part of the environment because some life components are contains it, similarly, amino acids, nucleic acids in RNA and DNA.  </span>
