  1. Density-dependent
  2. Density-independent

Density-independent factors are those factors that are not dependent on the density of the population to affect them. These factors are usually physical factors of the environment like;

  • Disasters
  • Flood and drought
  • Earthquake etc.

Therefore, III only (floods and drought) is an example of density-independent factor affecting population growth.

The number of electrons is equal to the number of protons thus making an atom electrically neutral. Protons and neutrons are located inside the nucleus of an atom while electrons are located outside the nucleus where they revolve round the nucleus in their orbits.
