1.
Which of the following is NOT one of Earth's major terrestrial biomes?
Correct Answer
C. Wetlands
Explanation
Wetlands is not one of Earth's major terrestrial biomes because wetlands are considered as transitional areas between aquatic and terrestrial ecosystems. They are characterized by saturated soil and waterlogged conditions, which are distinct from the other terrestrial biomes such as rainforests, deciduous forests, and tundra. Wetlands have unique hydrological and ecological features that support a diverse range of plant and animal species adapted to these specific conditions.
2.
Where are the most fertile soils found?
Correct Answer
B. Grasslands
Explanation
Grasslands are known to have some of the most fertile soils due to the presence of deep root systems of grasses. These deep roots help in the accumulation of organic matter and nutrients in the soil, making it highly fertile. Additionally, the frequent fires that occur in grasslands also contribute to the enrichment of the soil by releasing nutrients from burnt plant material. This combination of factors makes grasslands an ideal environment for the development of highly fertile soils.
3.
Deserts of the world are under which pressure system?
Correct Answer
A. Subtropical High
Explanation
The correct answer is Subtropical High. Deserts of the world are under the influence of the Subtropical High pressure system. This system is characterized by descending air, which inhibits cloud formation and precipitation. The sinking air warms and dries as it descends, creating arid conditions in the regions beneath the Subtropical High. This is why deserts are typically found in areas where this pressure system dominates.
4.
The native woodland of California is called
Correct Answer
D. Chaparral
Explanation
The correct answer is Chaparral because it is the native woodland of California. The Mojave Desert and Colorado Desert are both arid regions in California, while Sherwood Forest is a famous woodland in England. Therefore, the only option that accurately describes the native woodland of California is Chaparral.
5.
The largest terrestrial biome on Earth is the
Correct Answer
C. Taiga
Explanation
The taiga is the largest terrestrial biome on Earth. It is characterized by long, cold winters and short, cool summers. The taiga is dominated by coniferous forests, such as pine, spruce, and fir trees. It is found in the high latitudes of North America, Europe, and Asia. The taiga biome has a unique ecosystem with a variety of wildlife, including bears, wolves, moose, and birds. The harsh climate and short growing season limit the diversity of plant species, but the taiga is still an important habitat for many organisms.
6.
The soils of the Deciduous Forest contain lots of
Correct Answer
D. Humus
Explanation
Humus is the correct answer because it is a dark, organic material that forms in the soil as a result of the decomposition of plant and animal matter. It is rich in nutrients and helps to improve soil fertility, moisture retention, and overall soil structure. The presence of humus in the soils of the Deciduous Forest is important for supporting the growth of diverse plant species and providing a suitable habitat for many organisms.
7.
Arboreal animals are most commonly found in the
Correct Answer
B. Rainforest
Explanation
Arboreal animals are most commonly found in the rainforest because the rainforest provides a suitable habitat for these animals. The dense vegetation and tall trees in the rainforest offer ample opportunities for arboreal animals to live, feed, and move around. These animals have adapted to living in trees and have specialized features such as strong limbs, sharp claws, and prehensile tails to help them navigate and survive in this environment. The rainforest also provides a variety of food sources and shelter for arboreal animals, making it an ideal habitat for them.
8.
The following is true about the Tropical Savannah:
Correct Answer
C. The animals migrate in order to find water
Explanation
The correct answer is that the animals migrate in order to find water. This is because in the Tropical Savannah, there is a distinct wet and dry season. During the dry season, water becomes scarce and many water sources dry up. As a result, animals need to migrate to areas where they can find water to survive. This behavior is necessary for their survival in this type of ecosystem.
9.
The Tundra biome gets lots of snow.
Correct Answer
B. False
Explanation
The statement "The Tundra biome gets lots of snow" is false. The Tundra biome is characterized by extremely cold temperatures and a lack of precipitation, including snowfall. The cold climate prevents the accumulation of large amounts of snow, and instead, the Tundra biome is dominated by frozen ground and low-growing vegetation adapted to the harsh conditions.
10.
An adaptation of plants and animals found in Deciduous Forests is:
Correct Answer
D. All of the above
Explanation
The correct answer is "all of the above". This is because plants and animals in deciduous forests have adapted in various ways to survive in their environment. Plant leaves are broad and lightweight to maximize their surface area for photosynthesis and to catch sunlight efficiently. Many animals in deciduous forests hibernate during the winter months when food is scarce and temperatures are low. Additionally, plants in these forests drop their leaves when sunlight is limited during the colder seasons, conserving energy and nutrients. Therefore, all of these adaptations are observed in deciduous forests.
