Andre listed some properties of electromagnetic waves.
Marysya12 [62]

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.

Which statement best describes ecological succession?
Delicious77 [7]

The correct answer is it always occurs in a predictable pattern.

Ecological successsion is defined as a <em>change in the structure of species of an ecological community over a period of tim</em>e. The succession that begins in a new environment by uninfluence of pre-existing species is called primary succession. The disruption of pre-existing community because of succession is called secondary succession. Ecological succession happens in a predictable pattern. The ecological communities undergoes predictable change which creates a disturbance or initial formation of new habitat. This changes occurs in an orderly manner and can be best explained by the example of trees how they grow bigger and bigger.
