The bottleneck effect is when the population of a species is reduced due to an environmental disaster or human activities. An example of the bottleneck effect is "Insecticide spraying eliminates all but a few of the beetles on an island". For the species to survive, the green beetle will either have to move to a new location and build a new colony or they will have to develop a resistance to the insecticide and then start to rebuild the existing colony

The right answer is Electromagnetic waves can transfer energy through empty space.
Electromagnetic radiation refers to a form of linear energy transfer. Visible light is electromagnetic radiation, but is only a small slice of the broad electromagnetic spectrum. The propagation of this radiation does not need material to move.
if we take the example of solar energy, it spreads in space, the atmosphere until reaching the earth.
Once it reaches a material, it gives rise to many phenomena such as attenuation, absorption, diffraction and refraction, redshift, interferences, echoes, electromagnetic parasites and biological effects.
