Which abiotic factor is essential to all aquatic ecosystems except ocean hydrothermal vents, and why?

Phytoplankton, because it provides a source of food
salt, because it provides a source of minerals
deep water, because it provides the necessary environment for organisms to move about
sunlight, because it provides a source of energy

Water availability and temperature distinguish land biomes as _________ distinguishes aquatic biomes.

carbon dioxide concentration
salt concentration
oxygen level
phytoplankton abundance

Thank you Abigail

Thanks Abigail !!

Water availability and temperature distinguish land biomes as *salt concentration* distinguishes aquatic biomes.

nope none of thesse helppppp yalll need to give the coreect answers! next time!!!!!!!!!!!!!!!!!!!
