why do owls have large number of rod cells and few number of cones on the retina? please explain.

Cones are sensitive to bright light whereas rods are sensiive to dim light.As we know that Owls go in search of food at night.Therefore,they have more rods.

 rod cells helps to see in dim light and cones helps us to see in colour and in bright light. owl search food at night so yhey have more rods than cones

Cones are sensitive to bright light whereas rod cells are sensitive to dim light. As you are aware, owls usually go in search of food when it is almost dark. At that time, there is dim light and rod cells are required to see in dim light. Hence, rod cells are more in number. Owls don 't usually go out during the day so they need not have a large number of cones.

HOPE IT HELPS

 thanks to u all :)

Cones are sensitive to bright light whereas rod cells are sensitive to dim light.  owls usually stay awake in the night time and sleep in the day time . At the night time , there is dim light and rod cells are required to see in dim light. Hence, rod cells are more in number. Owls don 't usually go out during the day so they need not have a large number of cones.

 Shruti is correct

 iam correct

owl has large number of rod cells as rod cells responds to the brightness of light and owl are used to see in dim light

the rod cells helps them in seeing at night and they contain very few cones bcoz they sleep during morning time so they don't need a large no of cones for seeing in bright light.
