Biome - Correct Answer-A large region characterized by a specific type of climate and
certain types of plant and animal communities.
Savanna - Correct Answer-A tropical / subtropical grassland biome with scattered
individual trees, large herbivores, and three distinct seasons based primarily on rainfall,
maintained by occasional fires and drought.
Desert - Correct Answer-A region of little vegetation, either cold or hot, that receives ten
inches or less of precipitation each year, long periods without rain, deserts have
extreme temperatures.
Tundra - Correct Answer-Biome that surrounds the north and south poles; treeless
landscape with short, cool summers, and long, very cold winters with short periods of
winter sunlight, beneath the topsoil is a layer of permafrost.
Temperate Deciduous Forest - Correct Answer-Characterized by warm summers, cool
winters, has all four seasons, year-round precipitation and fertile soil.
Coniferous Forest - Correct Answer-Forest populated by cone-bearing evergreen trees;
mostly found in the colder northern latitudes.
Flora - Correct Answer-All the plant life in a particular region, or period.
Fauna - Correct Answer-All of the animal life in a particular region, or period.
Prarie - Correct Answer-A large area of flat land, or rolling hills covered by grasses and
wild flowers but few trees.
Temperate - Correct Answer-Climate zones with moderate (warm) temperatures that
are located between the tropics and the polar zones.
Permafrost - Correct Answer-A layer of permanently frozen subsoil found in the tundra
Alpine Tundra - Correct Answer-biome at high mountain altitudes, which has vegetation
& climate similar to those of the Arctic tundra
(though no permafrost)
Marine - Correct Answer-Biome that includes open ocean, seashore, and it covers 75%
of the planet. There is a very high salinity level, and a wide variety of animals

Estuary - Correct Answer-An area where fresh water from a river mixes with salt water
from an ocean; are productive ecosystems because they constantly recieve fresh
nutrients from the river and the ocean.
Forest - Correct Answer-Large tree and plant filled area that covers 30% of Earth's land
surface. Provide habitats, maintain soil, air, and water quality, acts as a carbon sink in
biogeochemical cycle.
Coral Reef - Correct Answer-A structure of calcite skeletons built up by coral animals in
warm, shallow ocean water.
Wetland - Correct Answer-An ecosystem in which water either covers the soil or is
present at or near the surface of the soil for at least part of the year.
Marsh - Correct Answer-A type of wetland featuring grasses, reeds and other plants in
shallow water.
Tributary - Correct Answer-A stream or river that flows into a larger river.
Freshwater - Correct Answer-Aquatic ecosytem that does not contain any saltwater, can
be rivers, lakes, streams,ponds, and wetlands.
Biosphere - Correct Answer-Consists of all life on Earth and all parts of the Earth in
which life exists, including land, water, and the atmosphere.
Organism - Correct Answer-Individual living thing.
Species - Correct Answer-A group of organisms that are closely related, who can mate
to produce fertile offspring. All of the cats are feline, but each cat is a different species.
Biodiversity - Correct Answer-The number, and variety of living organisms in a given
area, during a specific period of time.
Ecosystem - Correct Answer-A system formed by the interaction of a community of
organisms with their physical environment.
Habitat - Correct Answer-Place where an organism lives.
Niche - Correct Answer-An organism's particular role in an ecosystem, or how it makes
its living.
Abiotic - Correct Answer-All of the non-living parts of an ecosystem.
Biotic - Correct Answer-All of the living parts of an ecosystem.
Biomass - Correct Answer-Total amount of living tissue within a given trophic level.
