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 highest energy levels are filled last in an atom based on the Pauli exclusion principle and Aufbau principle. Electrons fill lower energy levels first before moving to higher energy levels.
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.
The 4s orbital should fill before the 3d orbital. This is because the 4s orbital has a lower energy level than the 3d orbital, according to the aufbau principle.
