photic

But plants, as we have seen, can grow only near the surface of the sea, in the photic zone.

Its origin lies in activities within the productive photic zone.

The photic response is likely linked to effects of light on circadian rhythms.

The photic zone covers the oceans from surface level to 200 metres down.

The study also showed that photic sneezing is more likely to be acquired than inherited.

The photic zone can be subdivided into two different vertical regions.

In this way, a sample can be collected across the whole photic zone where most ichthyoplankton is found.

The pelagic part of the photic zone is known as the epipelagic.

This is also known as the euphotic, or more simply as the photic zone.

The photic zone has sufficient light for phytoplankton to photosynthese.

They're beyond the photic exosphere of the star.

This behavior is known as the photic sneeze reflex, and researchers aren't exactly sure what causes it.

Day length and insolation intensity also controls the extent of the photic zone.

The photic zone exposed to sufficient sunlight for photosynthesis to occur.

The term deep sea creature refers to organisms that live below the photic zone of the ocean.

These patients do not need to produce conditions of intermittent photic stimulation for self-induction.

A flickering pattern called photic simulation, also known as flicker vertigo.

This limits phytoplankton photosynthesis to a relatively shallow photic zone.

Touch, photic and auditory stimulation are capable of affecting brain wave activity.

The depth of the photic zone can be greatly affected by seasonal turbidity.

Because the photic zone typically extends only a few hundred meters below the water, about 90% of the ocean volume is in darkness.

A photic sneeze is a sneeze that results from exposure to a bright light.

Photic sneezing can be combated by shielding one's eyes with hats or sunglasses.

It lies between the photic epipelagic above and the aphotic bathypelagic below, where there is no light at all.

Degradation of photic habitat by artificial light.
