They do not have five energy levels. Most have three and a very few have four. Starting at the first level with 100% energy, only 10% is passed to the second level, 10% of 10% or 1% is passed to the third level. If the energy at the first level is very good, there may be enough to go to the fourth level which is 0.1%. You may find 4 levels in tropical jungles or temperate rain forests.
Chemical symbol for yttrium is Y. it is in the 5th period. It has 5 energy levels.
5, i think
arsenic belongs to V-A group of periodic table it has 5 electrons in its outermost energy level.
3
Radon has six electron shells.
Biomass
Silver has 5 energy levels. 😄
Platinum has six energy levels.
Because the energy decreases on every level, so a triangle makes sense to show that there is less energy on the highest trophic levels.
Yes, it has 5 energy levels as it belongs to group 5. The 54 electrons in xenon are filled in these energy levels as 2, 8, 18, 18, 8

Yes, it does. In many ecological pyramids, the producer form the base and the successive trophic levels make up the rest. Energy pyramids are always slopping because less energy is transferred from each level than was paid into it.

The rows (periods) work out to be the energy levels, ex. if an element is in period 5, it has 5 energy levels.
