Biomes: End Of Units Prep Quiz

1.

A biome is determined by:

A.

Climate: temperature and precipitation.
B.

Climate: latitude and longitude.
C.

Climate and biogeography.
D.

Climate: temperature, wind and water.

Correct Answer
A. Climate: temperature and precipitation.

Explanation
A biome is determined by climate, specifically temperature and precipitation. These two factors greatly influence the types of plants and animals that can survive in a particular area. Temperature affects the rate of biological processes and determines the length of growing seasons, while precipitation determines the availability of water for plants and animals. Together, temperature and precipitation shape the overall climate of an area, which in turn determines the characteristics of the biome. Latitude and longitude, biogeography, temperature, wind, and water may also play a role in determining the climate, but the specific factors mentioned in the correct answer are the primary determinants.

A biome is:

A.

A group of land ecosystems with similar climates and organisms.
B.

A study of where organisms live.
C.

An ecosystem defined by latitude.
D.

The study of an ecosystems' latitude and longitude.

Correct Answer
A. A group of land ecosystems with similar climates and organisms.

Explanation
A biome refers to a group of land ecosystems that share similar climates and organisms. This means that within a biome, the climate and the types of organisms present are relatively consistent across different ecosystems. Biomes are characterized by factors such as temperature, precipitation, and vegetation, which determine the types of plants and animals that can thrive in these areas. Therefore, the correct answer is "A group of land ecosystems with similar climates and organisms."

All of the following are true of Boreal forests except:

A.

Most of the trees are coniferous.
B.

Tree species are well-adapted to cold climates.
C.

Trees are adapted to prevent water loss during the winter.
D.

Forest temperatures are moderate to warm and humid all year.

Correct Answer
D. Forest temperatures are moderate to warm and humid all year.

Explanation
Boreal forests are characterized by cold climates, and the tree species found in these forests are well-adapted to withstand these harsh conditions. These trees are also adapted to prevent water loss during the winter, as water availability is limited in cold environments. However, the statement that forest temperatures are moderate to warm and humid all year is not true for Boreal forests. These forests experience long, cold winters and relatively short, cool summers, with temperatures often dropping below freezing during the winter months.

Review the diagram. Answer the question below the diagram: Suppose 10,000 units of energy are available at the level of the grasses and trees. What is the total number of energy units lost by the time energy reaches the raptor?

A.

9990 units
B.

990 units
C.

90 units
D.

9900 units

Correct Answer
A. 9990 units

Explanation
The diagram represents an energy pyramid, where energy is transferred from one trophic level to another. Each level of the pyramid represents a different organism in the food chain. As energy moves up the pyramid, some of it is lost through metabolic processes, heat, and waste. In this case, the energy starts at the level of the grasses and trees with 10,000 units. By the time it reaches the raptor, which is at a higher trophic level, there is a loss of 10 units of energy. Therefore, the total number of energy units lost by the time it reaches the raptor is 9990 units.

One factor that has affected how species are distributed on Earth is:

A.

Continental drift.
B.

Pangaea.
C.

Dispersal.
D.

Biogeography.

Correct Answer
A. Continental drift.

Explanation
Continental drift refers to the movement of Earth's continents over time. This process has had a significant impact on the distribution of species on Earth. As continents have moved and separated, they have created barriers that have limited the ability of species to migrate and disperse. This has led to the development of distinct biogeographic regions and the evolution of unique species in different parts of the world. Continental drift has played a crucial role in shaping the current distribution patterns of species and has influenced their evolution and diversity.

Organisms may be dispersed (spread out in the environment) in all the following ways except:

A.

Wind.
B.

Water.
C.

Temperature.
D.

Other organisms.

Correct Answer
C. Temperature.

Explanation
Organisms can be dispersed through various means such as wind, water, and other organisms. However, temperature is not a method of dispersal. Temperature does not physically transport organisms from one location to another. It may affect the distribution of organisms by influencing their survival or reproductive rates, but it is not a direct mechanism of dispersal.

There are two rain forest biomes. One is temperate and deciduous (four-seasoned with leafy trees) and one is tropical (two-seasoned with varied plants and trees). They differ by location. Read the map, choose their correct location.

A.

Tropical rainforests are located in Europe and central Asia. A temperate rainforest - in located in the Pacific northwest US.
B.

Tropical rainforests can be found South America, Western Central Africa, Indonesia, Asia, Temperate-Pacific northwest US.
C.

Tropical rainforests can be found in the Midwest and Southern US. Temperate rainforests are found in the Pacific northwest US.
D.

None of these.

Correct Answer
B. Tropical rainforests can be found South America, Western Central Africa, Indonesia, Asia, Temperate-Pacific northwest US.

Explanation
The correct answer is that tropical rainforests can be found in South America, Western Central Africa, Indonesia, Asia, and the temperate rainforest is located in the Pacific northwest US. This answer accurately identifies the correct locations for both types of rainforests based on the information provided in the passage.

What is climate?

A.

Climate is the typical weather pattern of an area over a long period of time.
B.

Climate is the weather and latitude of a given area.
C.

Climate is the latitude and longitude of a given area.
D.

Climate is daily weather.

Correct Answer
A. Climate is the typical weather pattern of an area over a long period of time.

Explanation
Climate refers to the long-term weather patterns that are characteristic of a specific region. It encompasses the average temperature, precipitation, wind patterns, and other atmospheric conditions that occur over an extended period of time. Unlike daily weather, which can vary greatly from day to day, climate represents the overall trends and averages observed over many years. Therefore, the correct answer states that climate is the typical weather pattern of an area over a long period of time.

Apply your knowledge: Review the diagram. Answer the following question based on the diagram and what you understand about the relationship between biomes, latitude and elevation (height above sea level): Why do the biomes vary at different locations on a mountain?

A.

As elevation increases, climate temperature decreases. Climate becomes colder from the base of the mountain to its peak.
B.

As temperature decreases the biome climate changes.
C.

As slope and elevation increase, wind and precipitation increase, causing the climate to change.
D.

As slope and elevation increase, temperature and precipitation increase, causing climate to change.

Correct Answer
A. As elevation increases, climate temperature decreases. Climate becomes colder from the base of the mountain to its peak.

Explanation
As elevation increases, the temperature decreases. This is because as you go higher up a mountain, you are moving away from the warmer surface of the Earth and into the colder upper atmosphere. This change in temperature affects the climate, which in turn affects the types of biomes that can thrive at different elevations. Therefore, the biomes vary at different locations on a mountain because the climate changes with elevation.
