Solar energy
obviously
No, electrons fill the lowest energy levels first before moving to higher energy levels. This follows the Aufbau principle, which states that electrons occupy the lowest energy levels available to them before filling higher ones.
No, the tendency is to fill out lower energy levels first.
The first energy level can take a maximum of two electrons.
Yes, when their diet varies they can fill more than one trophic level
2
Electrons fill the 1st energy level first because it has the lowest energy and is closest to the nucleus. Electrons are attracted to the positively charged nucleus and fill the energy levels in order of increasing distance from the nucleus.
The principle is: electrons fill first the lower energy levels.

Biomes or ecosystems fill this description.
4s will fill first because it is at a lower energy level than the 3d level.
