ECOLOGY EXAM QUESTIONS AND
ANSWERS 2026 VERIFIED.
Biome - ANS A large region characterized by a specific type of climate and certain types of
plant and animal communities.
Savanna - ANS 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 - ANS 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 - ANS 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 - ANS Characterized by warm summers, cool winters, has all
four seasons, year-round precipitation and fertile soil.
Conifer - ANS Cone-bearing trees (ie: pine, or fir tree) of middle and high latitudes that are
mostly evergreen and that have needle-shaped or scale like leaves. Conifers are able to
withstand the long, cold winter season.
, Coniferous Forest - ANS Forest populated by cone-bearing evergreen trees; mostly found in
the colder northern latitudes.
Flora - ANS All the plant life in a particular region, or period.
Fauna - ANS All of the animal life in a particular region, or period.
Prarie - ANS A large area of flat land, or rolling hills covered by grasses and wild flowers but
few trees.
Temperate - ANS Climate zones with moderate (warm) temperatures that are located
between the tropics and the polar zones.
Permafrost - ANS A layer of permanently frozen subsoil found in the tundra
Alpine Tundra - ANS biome at high mountain altitudes, which has vegetation & climate
similar to those of the Arctic tundra
(though no permafrost)
Marine - ANS 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
Plankton - ANS A general term for the tiny, free-floating or weakly swimming organisms that
live in both freshwater and saltwater environments.
Estuary - ANS 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 - ANS 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.
