Biome multiple choice

which of the following statements is not correct

tropical rain forest are resistant to change because the plants contain so many nutrients

as you travel from the north pole toward the equator, you would expect to see

tundra, then grasslands, then tropical rain forests

which of the following is not characteristic of wetlands

wetlands are limited to inland freshwater environments

as they flow down a mountain to flatter ground, rivers generally become

wider, warmer, and slower

what mainly distinguishes nekton from benthos

one swims freely and the other often lives attached to a hard surface

which organism produces most of the food in the aquatic ecosystem

phytoplankton

estuaries are very productive ecosystems because they receive fresh nutrients from

rivers and oceans

which of the following statements is not correct

rivers generally move faster, and their oxygen levels decrease, as they near the ocean

which of the following adaptations are used by animals of the arctic tundra

rodents burrow underground for winter protection

which ecosystem has the highest level of salinity

salt marsh

adaptations of desert animals that help them survive in the hot, dry desert often include

searching for food

the majority of marine organisms are found in

shallow, coastal waters

biomes with higher temperatures and less precipitation tend to have

shorter and less dense vegetation

why doesn't photosynthesis occur in deep ocean water

there is no sunlight

chaparral plants usually survive fires because

they can resprout from small, leathery leaves

which of the following is an adaptation of coniferous trees in the taiga

they have leaves that retain water, due to their shape and waxy coating

which of the following is not true about temperate deciduous forest

trees grow lush green leaves in spring, but lose their leaves in late summer

the tundra

has a layer of soil that is permanently frozen beneath the top soil

which of the following id s threat to coral

oil spills, sewage, and pesticides

taiga is

a forest biome dominated by coniferous trees, such as pine, fur, and spruce

adaptations demonstrated by plants in tropical rain forest include

all the above

the types of organisms found in a pond or lake depend on

all the above

two threats to ocean ecosystems are

all the above

the arrangement of organisms in the open ocean is determined by the

amount of nutrients and sunlight that are available

estuaries

are ecosystems where both fresh and salt water are present

grasslands, such as the prairies of north america,

are threatened by soil erosion because native grasses have been damaged or destroyed by plowing and overgrazing

biomes

are usually described by their vegetation

animals that live in desert

are usually nocturnal

in what zone is the water cool and dark

benthic

which of the following is not characteristic of salt marshes and mangrove swamps

both are dominated by marsh grasses

which of the following is located primarily in costal areas that have Mediterranean-style climates with warm, dry summers and mild, wet winters

chaparral

tropical rain forest are determined by

deforestation and the trade of rain forest plants and animals

which of the following would you expect to see in the emergent layer of a tropical rain forest

eagles, bars, and snakes

what adaptations prevents phytoplankton from sinking into deep waters

flagella

swamps are commonly found on

flat, poorly drained land

the deforestation of the rain forests may cause climate changes, which, in turn, may affect

flooding

which of the following is not an environmental function of wetlands

increasing runoff

what causes most coastal pollution in the u.s.

industrial waste and sewage

most pollutants that enter estuaries break down over time, yet they are still considered a problem because

it is the volume of the pollutants, more than the time factor, that harms estuaries

if you visited a savanna, you would likely see

large herds of grazing animals, such as rhinos, gazelles, and giraffes

the distance north or south of the equator, as measured in degrees, is called

latitude

in what zone is life diverse and abundant

littoral

all of the following are characteristics of temperate rain forests except

low rainfall in summer but abundant snow in winter

wha are 2 main types of freshwater wetlands

marshes and swamps

deserts are

often formed on the dry side of mountain ranges

which of the following best describes a tropical rain forest

species of animals with specialized ways of surviving in order to avoid competition

the main factor that determines what type of plants grow in a biome is

temperature and precipitation

you are walking through a forest that gets large amounts of rain, has high humidity, and has moderate temperatures year-round. where might you be located?

the Pacific Northwest

an estuary functions as a mineral trap due to

the mixing action of river water and ocean water

coral reefs are intricately shaped rocklife structures that are formed as a result of

the secretion of calcium carbonate by tiny marine animals
