Increasing depths in the ocean causes a what in sunligh. Increasing depths in the ocean causes a what in pressure. Producer in the upper three zones of the ocean use what while producer in the lower ocean zones use what to generate nutrients to support the ecosystem

With increase in depth, sunlight decreases and pressure increases. Not sure what you are seeking for the last part.

Since this is not my area of expertise, I searched Google under the key words "ocean zones producers" to get these possible sources:

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search. Also see http://hanlib.sou.edu/searchtools/.

Increasing depths in the ocean cause a decrease in sunlight. To understand this phenomenon, we need to recognize that sunlight is composed of various wavelengths. As we move deeper into the ocean, these wavelengths are absorbed and scattered by water molecules and particles suspended in the water. The absorption and scattering processes reduce the amount of sunlight that reaches greater depths, resulting in diminished light availability.

Increasing depths in the ocean cause an increase in pressure. Pressure in the ocean increases with depth due to the weight of the water above exerting force. For every 10 meters of depth, the pressure increases by approximately 1 atmosphere (or about 14.7 pounds per square inch). This increase in pressure can be attributed to the weight of the water column pressing down on the deeper regions.

Producers in the upper three zones of the ocean, known as the euphotic zone, use sunlight as their primary energy source for photosynthesis. These producers include phytoplankton and algae, which convert light energy into chemical energy, thereby producing nutrients.

Producers in the lower ocean zones, such as the bathyal and abyssal zones, where light penetration is limited or absent, rely on alternate sources of energy. They utilize a process called chemosynthesis, which involves obtaining energy from chemical reactions rather than light. These producers, including chemosynthetic bacteria and certain types of tube worms, generate nutrients by utilizing chemical compounds such as hydrogen sulfide or methane, which are found in deep-sea hydrothermal vents or seepage areas.
