- The extremely low precipitation of subtropical desert biomes might lead one to expect fire to be a major disturbance factor; however, fire is more common in the temperate grassland biome than in the subtropical desert biome. Why is this?The extremely low precipitation of subtropical desert biomes might lead one to expect fire to be a major disturbance factor; however, fire is more common in the temperate grassland biome than in the subtropical desert biome. Why is this?It is especially important to prevent pollution within because water from throughout this region drains into lakes, rivers, or other bodies of water and degrades them. soils O watersheds groundwater aquifer bedrock

- Which of the following threats to terrestrial biomes is FALSE? O Exploration of oil and gas threaten both boreal forest and tundra ecosystems. O Climate change, farming practices, and overgrazing are leading to the desertification of tropical savannas. O Logging for timber poses a greater threat to tropical rain forests compared to effects of large-scale agriculture. O Human-mediated changes in the frequency and intensity of fire are threatening Mediterranean shrublands.productivity in above-ground biomass increment is greater in the estuarine stand than the island fringing stand productivity in litterfall is greater in the estuarine stand than the island fringing stand O productivity can be measured in part by measuring carbon in litterfall O productivity can be measured in part by measuring carbon in above-ground biomass increment subtracting above-ground biomass increment from litterfall provides the total productivity for a mangrove standMost vegetation was destroyed after a fire, but quickly started coming up afterwards due to a good combination of sun and rain. Predict which of the possibilities below would best describe this ecosystem as it was recovering from the fire.
