Which biome is also called the boreal or coniferous forest?
desert
tundra
taiga
savanna
Which land biome is characterized by dense vegetation, seasonally warm temperatures, and abundant rainfall? This biome is home to the majority of plant and animal species in the world.
rainforest
marine
deciduous forest
desert
This biome is characterized by areas of open grassland with very few trees. Several large land animals inhabit this biome including elephants, giraffes, zebras, and rhinoceros.
tundra
savanna
desert
boreal forest
This biome is determined by extremely low amounts of rainfall, not temperature. The climate can be either extremely cold or extremely hot.
temperate forest
tropical rain forest
grasslands
desert
This biome is home to a variety of deciduous (lose their leaves in winter) trees.
tundra
rainforest
savanna
temperate forest
Which biome is characterized by extremely cold temperatures, treeless landscapes, and land that remains frozen year-round?
grassland
tundra
rainforest
taiga
Grasslands are located on every continent EXCEPT...
Africa
Australia
Antarctica
South America
Which of the following situations contributes to stability in an ecosystem?
increase biodiversity
extinction of a population from the ecosystem
reduction in biodiversity
removal of many populations of organisms
Ants and acacia trees have a mutualistic relationship because...
they benefit each other.
they are both adapted to a humid climate.
they are part of the same ecosystem.
the ants eat part of the acacia tree.
What is the MOST serious threat to biodiversity?
climate change
pollution
---> LOSS OF NATURAL HABITAT <---
global warming
Complete this statement. The more DIVERSE an ecosystem is --
the more threatened its populations are.
the more stable it is.
the more similar the species will be.
the fewer the varieties of species are present.
Why do plants that grow in the tundra have shallow root systems?
They have no soil in which to grow.
They cannot grow through the permafrost.
They are frequently soaked with heavy rains.
They are trampled on each time animals migrate.
In which biome would you expect to find a permafrost layer?
taiga
tundra
grassland
savanna
A researcher is investigating the plants shown. Which biome is the researcher most likely studying?
taiga
desert
grassland
rainforest
How is the tundra biome similar to a desert biome?
Both biomes have dry, rocky soils.
Both biomes lack plants and animals.
Both biomes are hot during the day and cold at night.
Both biomes are characterized by very little precipitation.
Which is an example of a biome?
a cave
an old tree
a large lake
a tropical rainforest
Which of the following factors determines a biome's identity?
the climate that exists there
the number of people that live there
the amount of pollution that occurs there
the types of activities that can be done there
In which biome would you expect to find many coniferous trees?
taiga
tundra
savanna
rainforest
What is an adaptation that allows some animals to survive in the tundra?
living underground
having thick layers of fur
being only active at night
living within the upper branches of trees
Which of the following statements about biodiversity is TRUE?
More biodiversity = Less chance for an ecosystem to sustain itself
More biodiversity = Better chance for an ecosystem to sustain itself
More biodiversity = Less species in an ecosystem
More biodiversity = More pollution in an ecosystem
Many plants have a waxy coating to keep water from escaping. What type of adaptation is this?
structural
behavioral
physiological
Which forest has trees that lose their leaves every year?
rainforest
boreal forest
deciduous forest
marine forest
What is one way the tundra differs from the taiga?
The taiga has permafrost and the tundra doesn't
The taiga is abundant in evergreens and the tundra is mostly bare
The tundra is cold all year and the taiga is warm all year
The animals are adapted for the cold in the tundra but not the taiga
The graph shows how much rain fell in six different biomes last year. What is one conclusion you can make based on the information in the graph?
More rain fell on grasslands compared to the taiga.
The desert and tundra received about the same amount of rain last year.
Tropical rainforests received about 20 extra inches of rain compared to the tundra last year.
The taiga and temperate deciduous forest received about the same amount of rain last year.
Marine ecosystems are saltwater? TRUE or FALSE?
True
False
