Answer • Climate • Temperature • Precipitation Question • What type of climate (temperature and precipitation) would a biome with a high net primary production have? Answer • Warm climate, lots of precipitation (wet) Question • Biomes are a group of ____________ that share similar biotic and abiotic factors. Answer • Ecosystems Question • What describes average conditions, temperature and precipitation, over long periods in a given area? Answer • Climate Question • Climatographs are useful tools in describing a biome’s climate. They typically show patterns in annual __________ and ____________. Answer • Temperature and precipitation Question • What is the extended period of deep, sleeplike inactivity that an animal enters for winter? Answer • Hibernation Question • What type of trees experience seasonal loss leaves as an adaptation to their climate? Answer • Deciduous Question • What is the frozen underground soil called that is found in the tundra? Answer • permafrost Question • The farther you travel from the equator, the colder temperatures get. This is why areas located at similar _________ tend to be classified as the same biome. Answer • latitudes Question • What is the day-to-day conditions in Earth’s atmosphere like “sunny and humid” or “cold and snowy” called? Answer • Weather Question • ________ ___________ results in the survival and reproduction of organisms best suited to their current environment. Answer • Natural Selection Question • For a given biome, which would be greater, gross primary production or net primary production? Answer • Gross primary production Question • Net primary production is the organic matter or biomass, that remains after ________ _____________. Answer • Cellular respiration Question • Which biome receives more rain than any other biome? Answer • Tropical rain forest Question • What are plants that grow on other plants rather than in the soil called? Answer • Epiphytes Question • What is a deep, sleeplike, period of dormancy some animals enter in response to dry conditions? Answer • Estivation Question • Why is migration so common in the savanna? Answer • Animals need to move around in search of available water Question • In which biome do plants typically have large flat leaves in order to maximize the available amount of sunlight? Answer • Tropical rain forest Question • Which is the driest biome on Earth? Answer • The desert Question • The largest extent of this biome occurs in the Pacific Northwest coast of the United States.

Answer • Flood Plain Question • What are bodies of water that occur where rivers flow into an ocean or inland sea called? Answer • Estuaries Question • Which horizontal zone of the ocean extends out from the low tide mark to the edge of the continental shelf? Answer • Neritic Zone Question • What are areas of land that are flooded with water at least part of the year called? Answer • Wetlands Question • Organisms that have adaptations that enable them to avoid being carried away by swift currents are more likely to live near the source or mouth of a river? Answer • Source Question • Water in an estuary is said to be _______ because it is a mixture of freshwater and saltwater. Answer • Brackish Question • In which horizontal zone of the ocean must organisms be adapted to tremendous extremes in temperature, salinity, moisture, and sun exposure. Answer • Intertidal Zone Question • List up to 4 types of wetlands.
