What exactly is the question here? Please answer so i can help you! :)
Answer:
Most food webs have between 4 and 5 trophic levels
Explanation:
Energy flow: From the whole quantity of energy that reaches the earth's surface, autotroph organisms or producers only absorb 0.1 or 1%.
From the input of solar energy begins a unidirectional energy flow. It passes through all the organisms in the ecosystem, from autotrophs to heterotrophs, until it is eventually dissipated in the environment.
There is an energy transfer from each trophic level to the next, and each level only uses 10% of this energy. This assessment is called "The 10% rule". As a general rule, only about 10% of the energy stored as biomass at one trophic level, per unit time, ends up as biomass at the next trophic level, in the same unit of time. The rest of the energy is used by the organisms in their own metabolism or dissipated as heat to the environment.
The progressive reduction of energy determines the number of trophic levels, which, in general, turns to be between 4 and 5.
<span>Amniotic cavity is the term used for the sac which protects
an embryo from internal and external pressures. It contains the amniotic fluid which
serves as the cushion for guarding the developing embryo and the system to
which it is being fed on. It is a crucial part of pregnancy to be able to take
tests in diagnosing the fetus for possible defects and abnormalities and one of
the methods used is the amniocentesis wherein samples of the amniotic fluid are
sampled.</span>
