6 World Ecosytems What are the effects of fire on the environment (3)? What are some of the fire-adapted ecosystems? Why would humans set fires? Why might it be bad to suppress fires? Wildland-Urban Interface Fire Prescribed Burns Climate Biomes What are the two factors of climate? Alpine Tundra What is the climate like in the tundra? Describe the soil in the tundra. Permafrost Describe the landscape of the tundra. Species richness Primary productivity What are the common plant species in the tundra? What are the common animal species in the tundra? Where is the taiga located? What is the climate like in the taiga? Describe the landscape of the taiga/boreal forest. What are the common plant species in the taiga? What are the common animal species in the taiga? Describe the soil in the taiga. What products does the taiga yield? Were are temperate rain forests found? What is the climate of the temperate rain forest? Describe the soil in the temperate rain forest. What are the dominant plant species in the temperate rain forest? Monoculture Why are monoculture forests inferior to old growth forests? What is the climate of the temperate deciduous forest? Leach What are the dominant plant species of the temperate deciduous forest? What are the animal species in the temperate deciduous forest? What are the uses of the temperate deciduous forest? What is the climate of the temperate grassland? Describe the soil of the temperate grassland. Where do tall grassland prairies occur? What are the primary animals of the grasslands? How are shortgrass prairies different than tallgrass prairies? What is the grassland so important to agriculture? Where do chaparral occur? Describe chaparral soil. What is the main vegetation of a chaparral? What are the main animal species of a chaparral? How do fires play a role in the chaparral? What is the climate of a desert? Describe the soil of a desert. Describe the vegetation of a desert. Describe the typical desert animals. How have humans altered the desert? What is the climate of a savanna? Describe the soil of a savanna. Describe the vegetation of the savanna. What are the animal species of the savanna What are savannas currently being usef for? Desertification What is the climate of a tropical rain forest? Describe the soil of a tropical rain forest. What stimulates high productivity in the tropical rain forest? What are the three distinct layers of vegetation in the tropical rain forest? Epiphytes Where do most of the organisms in the tropical rain forest live? What are the animal species in a tropical rain forest? What human factors have destroyed the tropical rain forest? What is the connection between elevation and latitude? How do elevations and latitudes affect the types of organisms found in each place? How are aquatic ecosystems divided? Salinity Dissolved oxygen What factors determine the species composition in an aquatic ecosystem? What are the three main ecological categories of organisms Plankton What are the two types of plankton? Give definitions. Nekton Benthos What are the freshwater ecosystems? Why are freshwater ecosystems important? Flowing water ecosystem Source Headwater What force in a river affects the types of organisms the water has? Where does the energy of the headwaters come from? How have humans affected rivers and streams? Standing-water ecosystems What are the zones of a large lake? Littoral zone Limnetic zone Profundal zone Thermocline Thermal stratification Fall turnover Spring turnover Blooms Freshwater wetlands How are marshes and swamps different? Describe the soil of a wetland. Why are wetland such important environments? Ecosystem services What were wetlands once viewed as? Estuaries What must estuarine organisms tolerate. Why are estuaries among the most fertile ecosystems in the world? (4) Salt Marshes What is happening to salt marshes? Mangrove forests How are mangrove plants important to organisms? How are mangrove forests under assault? Describe the area of the Chesapeake Bay. Why has the Chesapeake Bay suffered in recent years? Chesapeake Bay Program What are some of the changes that have been made because of the Chesapeake Bay Program? What problems still remain in the Chesapeake Bay? What factors make the freshwater ecosystems very different from the saltwater ecosystems? What are the zones of marine environement? Intertidal zone Describe some organisms and their characteristics in the intertidal zone? Benthic Abyssal Benthic Zone Hadal Benthic Zone Sea Grasses Why are sea grasses ecologically important? Kelps Coral reefs Zooxanthellae What are the three types of coral reefs? What terrestrial biome is the coral reef comparable to and why? Why are coral reefs ecologically important? How have humans impacted the coral reefs? Bleaching Describe the coral/zooxanthellae relationship. Neritic province Euphotic zone Oceanic province Marine Snow Describe and define the major threats to the ocean environment. What are the three ways that the US Commission on Ocean Policy suggest we improve oceans? Describe the Everglades. What are the environmental problems of the Everglades? How did the Hoover Dike affect the Everglades? Why and how is the water diverted from this area? What are the 3 major parts of the Everglades plan? Comprehensive Everglades Restoration Plan
