Which of these factors will affect a population regardless of the populations density ? PLEASE HELP

Density independent factors affect populations regardless of their size. Examples are winter, drought, forest fires. These factors are mostly abiotic (non-living). Predation affects population size.

the circled areas are referred to   as sunspots.   the sunspots are cooler than the   surrounding area.

sunspots are temporary phenomena on the photosphere of the sun that appear visibly as dark spots compared to surrounding regions. they correspond to concentrations of magnetic field flux that inhibit convection and result in reduced surface temperature compared to the surrounding photosphere.
