A dense growth of plant life in a aquatic ecosystem which many animals living there die(due to lack of enough oxygen present in water) and the ecosystem gets completely disrupted. 
Eutrophication excessive richness of nutrients in a lake or other body of water, frequently due to run-off from the land, which causes a dense growth of plant life.

The dual nature of light is the property of light where it has both wave and particle properties.
The wavelength properties of light are such that light behaves as a set of electromagnetic waves that have different wavelengths.
The electromagnetic spectrum is the whole range of frequencies and wavelengths of electromagnetic waves.
<h3>What is the wave-particle dual nature of light?</h3>
The wave-particle dual nature of light is the property of light where it has wave-like properties such as reflection, refraction, diffraction, etc., and also has particle properties such as the photoelectric effect.
The wavelength of light is the distance between successive points in the wave.
The whole range of frequencies and wavelengths of light gives the electromagnetic spectrum.
