Seasonal fires are important to savanna biodiversity but they are not in temperate grasslands

The savanna is dominated by grasses while the temperate grassland has scattered trees

The savanna can be further categorized into prairies and steppes while the temperate grassland cannot

Seasonal fires are important to temperate grassland biodiversity but they are not in the savanna

Marine biomes have high salt concentration while freshwater biomes have low salt concentration

Freshwater biomes have high salt concentration while marine biomes have low salt concentration

Freshwater biomes contain algae that supplies most of the Earth’s oxygen, while marine biomes do not

Freshwater biomes are greater oxygen sinks than marine biomes
