Question 1

What is the main difference between short and tall grass prairies ?
A)One is dominated by grasses and the other is dominated by forbs.
B)Tall grass prairies receive more rainfall than short grass prairies.
C)Short grass prairies occur in warmer latitudes than tall grass prairies.
D)Tall grass prairies typically have colder winters than short grass prairies

Accepted Answer

The main difference between short and tall grass prairies is the amount of rainfall they receive. Tall grass prairies typically receive more rainfall than short grass prairies, which allows for the growth of taller grass species. Short grass prairies, on the other hand, have adapted to drier conditions and support shorter grass species.

Question 2

Which biome is most suitable for the development of farmland ?
A)taiga.
B)tropical rain forest
C)temperate grassland.
D)chaparral.

Accepted Answer

Temperate grasslands, also known as prairies, are the most suitable biome for the development of farmland. These areas have deep, fertile soils that are ideal for growing crops. They also receive sufficient rainfall to support agriculture, but not so much that it leads to soil erosion. The vegetation in temperate grasslands is dominated by grasses and other herbaceous plants, which can easily be cleared for planting crops. In contrast, taiga and tropical rainforests have acidic and nutrient-poor soils, respectively, making them unsuitable for agriculture. Chaparral regions are prone to wildfires, making them a riskier choice for farmland development.

Question 3

Correctly order the following from wettest to driest regions.
A)tall grass prairie,temperate desert,short grass prairie
B)short grass prairie,tall grass prairie,temperate desert
C)temperate desert,short grass prairie,tall grass prairie
D)tall grass prairie,short grass prairie,temperate desert

Accepted Answer

Tall grass prairies receive more rainfall than short grass prairies, which in turn receive more rainfall than temperate deserts. This makes D the correct order from wettest to driest.

Question 4

Where do Chaparral biomes occur ?
A)Only in the immediate area surrounding the Mediterranean Sea.
B)In regions with low levels of annual precipitation.
C)In areas with very fertile soil and a deep topsoil layer.
D)In regions around the globe with mild,wet winters,followed by hot,dry summers.

Accepted Answer

The answer of Where do Chaparral biomes occur ?
A)Only in...

Question 5

Why is tall grass prairie North America's rarest biome ?
A)Historically it only occurred in a very tiny region of North America.
B)Because over 90% of this biome has been converted to agriculture
C)Global warming has resulted in the conversion of most tall grass prairie to short grass prairie.
D)Pollution has degraded most of our tall grass prairie region.

Accepted Answer

Tall grass prairie has been extensively converted to agricultural land, with over 90% of the biome being lost. This makes it North America's rarest biome.

Question 6

Which biome has considerable organic material in the soil,annual precipitation of 10-30 inches,and periodic wildfires to maintain the dominant vegetation ?
A)temperate deciduous forest.
B)chaparral.
C)temperate grassland.
D)boreal forest.

Accepted Answer

The answer of Which biome has considerable organic material in...

Question 7

Which of the following organizational hierarchies is correct?
A)ecosystem landscape community biome
B)biome community landscape ecosystem
C)community ecosystem landscape biome
D)landscape community ecosystem biome

Accepted Answer

The correct order in ecological organization is from smallest to largest: organism, population, community, ecosystem, biome, and finally biosphere. Therefore, the correct order in this list would be community (a group of interacting populations), ecosystem (living and nonliving components in a defined area), landscape (a heterogeneous area with distinct physical features), and biome (a large geographic area with similar climate and vegetation). Hence, the correct order is community ecosystem landscape biome, which is option C.

Question 8

Which set of three parameters has the MOST effect on biome distributions?
A)latitude,longitude,precipitation
B)precipitation,longitude,temperature
C)temperature,latitude,climate
D)latitude,precipitation,temperature

Accepted Answer

Latitude, precipitation, and temperature are the most influential factors in determining biome distributions. Latitude affects the climate and temperature of a region, precipitation determines the availability of water, and temperature influences the types of plants and animals that can survive in an area. Longitude has less impact on biome distributions compared to these three factors.

Question 9

What distinguishes a savanna from other types of grasslands ?
A)Warm dry summers and cold dry winters
B)Widely scattered trees or clumps of trees
C)Large grazing herbivores
D)Large predators

Accepted Answer

The feature that distinguishes a savanna from other types of grasslands is the presence of widely scattered trees or clumps of trees. While warm dry summers and cold dry winters, large grazing herbivores, and large predators can be found in other types of grasslands, they are not unique to savannas.

Question 10

Which of the following is characteristic of desert animals ?
A)They tend to be quite large in size.
B)They remain inactive during the driest months of the year.
C)They are active throughout the day and night.
D)Rodents are the only group of mammals represented in this biome.

Accepted Answer

Desert animals often remain inactive during the driest months to conserve water and avoid the extreme heat, which is a survival strategy known as estivation.

Question 11

Which of the following is the best definition of a biome?
A)A distinct aquatic ecosystem,surrounded by wetlands and terrestrial upland.
B)A large distinct terrestrial region similar climate,soil,organisms,regardless of its global location.
C)One of several types of forests occurring across the globe.
D)A natural association that consists of all the populations of different species that live and interact together within an area at the same time.

Accepted Answer

The best definition of a biome is a large distinct terrestrial region with similar climate, soil, and organisms, regardless of global location. Option A describes a wetland ecosystem, while Option C describes a specific type of biome (forest) rather than the broad concept of a biome. Option D describes a community, not a biome.

Question 12

Which of the following would be considered a biome?
A)Lake
B)bay
C)Meadow
D)Desert

Accepted Answer

The answer of Which of the following would be considered...

Question 13

Which biome is characterized by hot summers and cold winters,topsoil rich in organic material,annual precipitation of 75 to 125 cm (30-50 in),and many hardwood trees ?
A)temperate deciduous forest.
B)temperate grassland.
C)temperate rain forest.
D)boreal forest.

Accepted Answer

The characteristics listed, including hot summers and cold winters, rich topsoil, and hardwood trees, are all typical of the temperate deciduous forest biome. The other biomes listed do not have all of these characteristics.

Question 14

Which of the following biomes has the HIGHEST biodiversity?
A)boreal forest
B)temperate grassland
C)temperate rain forest
D)tropical rain forest

Accepted Answer

Tropical rain forests have the highest biodiversity of all the biomes. They have the highest number of species of plants and animals, as well as the highest levels of primary productivity. The warm, wet and stable climate, combined with the large variety of both flora and fauna, create ideal conditions for a high level of biodiversity.

Question 15

Which of the following is a biological control that is used to suppress wild fires in chaparral ?
A)viral diseases
B)goats
C)introduced species
D)insect herbivores

Accepted Answer

Goats are used as biological control to suppress wild fires in chaparral by grazing on the vegetation, which reduces the amount of fuel available for fires. Viral diseases, introduced species, and insect herbivores are not effective biological controls for wild fires in chaparral ecosystems.

Question 16

Which of the following biomes is characterized by moist winters and hot,dry summers ?
A)temperate grassland
B)desert
C)tundra
D)chaparral

Accepted Answer

The chaparral biome is characterized by moist winters and hot, dry summers. This biome is typically found in areas with a Mediterranean climate, such as California and parts of Australia.

Question 17

How are temperate rain forests and the boreal forest similar?
A)Both have mild winters
B)Both are dominated by conifers
C)Both have tree species that are drought adapted
D)Both experience dense fogs

Accepted Answer

Both temperate rain forests and the boreal forest are dominated by conifers. While they have different tree species, they share this characteristic. The other options are not true for both types of forests.

Question 18

Which of the following statements about wildfires is TRUE ?
A)They are always damaging for natural environments.
B)They release nutrient minerals that were locked in dry organic material.
C)They encourage the growth of shade-resistant plants.
D)They result in the destruction of the underground stems and buds of grasses.

Accepted Answer

Wildfires release nutrient minerals that were locked in dry organic material, which can be beneficial for the growth of new vegetation. While wildfires can be damaging and destructive, they also play an important role in the natural ecosystem by promoting new growth and diversity. Option A is incorrect because some plants actually rely on wildfires to spread their seeds and rejuvenate their populations. Option C is incorrect because wildfires often create conditions where shade-tolerant plants cannot thrive. Option D is incorrect because grasses typically have deep roots that can survive underground even after a wildfire.

Question 19

What type of trees would you expect to find in a boreal forest?
A)coniferous
B)deciduous
C)temperate
D)hardwoods

Accepted Answer

Boreal forests, also called taiga, are dominated by coniferous trees such as spruce, fir, and pine. These trees are adapted to cold and snowy winter conditions and have needle-like leaves that allow them to photosynthesize even during the winter months. Deciduous trees, hardwoods, and temperate trees are not typically found in boreal forests.

Question 20

Which the following is found in tropical rain forests,but not in temperate rainforests?
A)amphibians
B)epiphytes
C)evergreen trees
D)relatively constant temperature

Accepted Answer

The answer of Which the following is found in tropical...
