Final answer:
Fire is more common in temperate grassland biome due to dense vegetation and lower precipitation levels. Subtropical desert and Arctic tundra are similar in their low temperatures and sparse vegetation. Option d is correct.
Explanation:
The reason fire is more common in the temperate grassland biome than in the subtropical desert biome is due to the difference in vegetation and precipitation. Grasslands have dense vegetation that promotes fires, whereas deserts lack sufficient vegetation for fire to spread easily. Additionally, grasslands have lower precipitation levels, which increases the likelihood of fires.
On the other hand, subtropical deserts and Arctic tundra share similarities in low temperatures and sparse vegetation. Both biomes experience harsh climates, with limited precipitation and cold temperatures. These conditions result in adaptations by plants and animals to survive in these extreme environments.
The reason fire is more common in the temperate grassland biome than in the subtropical desert biome is due to differences in vegetation density and moisture levels.
Grasslands have high levels of biomass because of dense vegetation consisting mostly of grasses, which, along with frequent lightning strikes, makes these areas prone to fires. In contrast, subtropical deserts have significantly less biomass due to lower net primary productivity; hence, there is not enough fuel to sustain fires.
One similarity between the subtropical desert and the Arctic tundra biomes is the scarcity of vegetation due to extreme climate conditions. Both biomes have low net primary productivity, which means they both support fewer life forms compared to other biomes like tropical rainforests or temperate forests.
