Answer 1

$\huge{\underline{\sf{\green{Answer-}}}}$

Effect of light in ocean water:-

More than 10% of incident light is lost by reflection.

Penetration gradually decreases as depth increases. depending on light penetration, the water bodies can be diveded into three zones:-

_______________________________________________________________

• Euphotic zone:- the upper most zone extends from surface to roughly 80 meters, maximum penetration of light. Most autotrophs are present in this zone.

• Diphotic zone :- middle region extends from 80 to upto 200m.light penetration decreases and light is diffused. Low level consumers found in this region.

• Aphotic zone :- last zone found below 200 metres, no light penetration. Predators and decomposers are found in this zone.

Answer 2

Explanation:

Yet exposure to light can result in cumulative and permanent damage to light-sensitive objects. Low light levels over a long period of time can cause degradation equal to or even greater than intense light for a short period. Damage occurs because light is radiant energy.
