euphotic उदाहरण वाक्य
उदाहरण वाक्य
- The euphotic depth is the depth at which light intensity falls to 1 % of the value at the surface.
- Maximum numbers of bacteria generally occur at the pycnocline, where phytodetritus accumulates by sinking from the overlying euphotic zone.
- The supply of nutrients, primarily nitrates, to the euphotic zone is thought to impact levels of dissolved oxygen.
- The biological pump is the conversion of particulate organic matter in the euphotic zone and transference to the deeper ocean.
- This restricts the symbiotic organism to euphotic habitats and requires consistent exposure to high levels of ultraviolet radiation ( UVR ).
- At the euphotic depth, plants ( such as phytoplankton ) have no net energy gain from photosynthesis and thus cannot grow.
- Yet during winter convective mixing, nutrients penetrate the euphotic zone, causing a short-lived phytoplankton bloom in the spring.
- Typical euphotic depths vary from only a few centimetres in highly turbid eutrophic lakes, to around 200 meters in the open ocean.
- Positive values indicate regions where oxygen has been consumed to concentrations below its euphotic waters by primary production and the resulting oxygen evolution.
- Ammonium and nitrite show a maximum concentration at 50 80 m ( lower end of the euphotic zone ) with decreasing concentration below that depth.
