Which of the following might be an investigation of microclimate? O exploring the density of rabbits in the Baldwin Hills behind West LA Campus O studying the temperature and humidity in a city park compare to the rest of the city researching the impact of seed harvesting ant species on the distribution of grasses O comparing tropical rainforests in South America with tropical rainforest in South Fast

Describe the vegetation of 3 of the Biomes. How does climate impact what type of vegetation is found in the given biomes?

Forest fires are key to shaping the ecosystem of Yellowstone National Park. Fires add more nutrients to the soils and can aid in seed germination. After a fire burns down many of the trees in an area, new vegetation takes over. This new vegetation is mostly various grass species that did not grow in the area before the fire. Which of the following is a biotic explanations for why the grasses did not grow in the area before the fire? select the best answer O The grass seeds were not able to get blown into the forest before the fire. O The shrubs and trees were better competitors for sunlight that is needed for grasses to grow The fire helped to add nutrients into the soil that is required for the grasses to grow O Hot temperatures from the fire is needed for grass seeds to germinate

Given these large-scale climate patterns based on latitude, what might you expect in terms of the global distribution of primary productivity (e.g. where might you expect greater plant productivity)? (Select all that are true.) Higher productivity near equator because of more direct solar radiation. Higher productivity near equator because of overall more precipitation. Bands of lower productivity near 30° N and S because of drier air. Bands of lower productivity near poles because of drier air.

An effective way to reduce future atmospheric warming would be to reduce international trade protect tropical rainforests and help them to regrow document all of the biodiversity in areas prior to development tightly regulate economic growth reduce infectious diseases spread by animals

Identify the coldes, driest biome with relatively little or relatively small vegetation. The plants in this biome have characteristically short "growth habits," meaning that species like willows and other trees may be only a few inches tall. Desert Temperate rainforest Savanna Tropical rainforest Tundra

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.

Which of the following BIOTIC influence or potentially determine the vegetation biome of a terrestrial region?     Grazing     Amount of rainfall     Mean temperature/length of growing season     Mean temperature/length of growing season

Which of the following accurately describes life in soils?   A: Soil food webs lack complexity compared to above-ground ecosystems. B: Soils contain both decomposers and predators that perform important functions. C: We would need to collect a large soil sample size to find many species. D: Soil biota sometimes support plants in taking up nutrients. E: B and D. F: B, C, and D.
