oxidation of sulfur by bacteria in ocean vent communities

photosynthesis by phytoplankton

respiration by zooplankton

They are permanently frozen

They are nutrient rich due to leaf litter from winter

They are identical to grassland soils

They are nutrient poor due to high competition from plant species

Freshwater and marine biomes are evenly distributed on Earth.

Freshwater biomes are a vital source of drinking water.

Freshwater biomes supply a greater portion of Earth’s oxygen than marine biomes

Marine biomes include streams, rivers, ponds, and lakes.
