Major Biomes Of Canada

The correct answer is Thundra because permafrost refers to a layer of permanently frozen soil, and the tundra biome is known for having this characteristic. The tundra is a cold and treeless biome found in the Arctic and high mountain regions, where the ground remains frozen year-round. This frozen soil prevents water from draining, resulting in the formation of marshes, ponds, and bogs.

Grassland is the correct answer because it is a biome characterized by vast areas of grasses and herbaceous plants. It is a dominant human activity because grasslands are often used for agriculture, particularly for grazing livestock and growing crops. The open landscape and fertile soil make grasslands suitable for farming, making agriculture a prominent human activity in this biome.

The majority of desert biomes are located in Africa. Africa is home to several well-known deserts such as the Sahara Desert, the largest hot desert in the world, and the Namib Desert, one of the oldest deserts on Earth. These deserts are characterized by their arid climate, extreme temperatures, and sparse vegetation. The unique geographical features and weather patterns in Africa contribute to the formation and maintenance of desert biomes in this region.

The correct answer is hot and dry. The desert biome climate is characterized by high temperatures and low precipitation. Deserts typically have very little rainfall and are known for their arid conditions. The lack of moisture and high temperatures create a hot and dry environment, making it difficult for many plants and animals to survive.

The given statement suggests that the dominant vegetation in the biome is composed of pine and spruce trees. Among the options provided, the biome that is known for having pine and spruce trees as dominant vegetation is the Coniferous Forest. Coniferous forests are characterized by their cold climate and are typically found in regions with long, cold winters and short summers. The trees in these forests have needle-like leaves that help them conserve water and withstand the harsh conditions. Therefore, the correct answer is Coniferous Forest.

The tundra biome has the least biodiversity because it is characterized by extreme cold temperatures, low precipitation, and a short growing season. These harsh conditions limit the variety of plant and animal species that can survive in this biome. The tundra is mostly covered in permafrost, which restricts the growth of trees and vegetation. As a result, the tundra has a limited number of plant species and supports only a small number of herbivores and carnivores.

Temperate rain forests are characterized by uniformly high temperatures and precipitation. These forests are found in regions with mild, wet climates, such as the Pacific Northwest of North America. The combination of high temperatures and abundant rainfall creates a lush and diverse ecosystem, with dense vegetation and a variety of plant and animal species. The consistent rainfall and moderate temperatures throughout the year support the growth of tall trees and a thick understory, making temperate rain forests one of the most productive biomes on Earth.

Biodiversity refers to the variety of different species of plants, animals, and microorganisms that exist in a particular environment. It encompasses the range of ecosystems, habitats, and genetic diversity within a given area. This answer accurately describes biodiversity as the presence of different animals in one environment, highlighting the importance of species diversity for a healthy and balanced ecosystem.

Winter weather in the tundra can last up to 9 months. The tundra is a region characterized by extremely cold temperatures and a short growing season. It experiences long, harsh winters with freezing temperatures and snowfall that can last for the majority of the year. The prolonged winter season in the tundra is due to its high latitude and proximity to the poles, resulting in limited sunlight and colder temperatures for an extended period.

The maple tree does not grow in the tundra because it requires a temperate climate and cannot survive the extreme cold temperatures and harsh conditions of the tundra. Lichens, moss, and grass, on the other hand, are well-adapted to the tundra environment and can thrive in the cold climate.

The type of biome a region has is determined by the climate. Climate refers to the long-term weather patterns of a region, including factors such as temperature, precipitation, and humidity. These climate factors greatly influence the types of plants and animals that can thrive in a particular area, which in turn determines the type of biome present. Different biomes, such as deserts, rainforests, or grasslands, have distinct climate characteristics that support specific types of ecosystems. Therefore, climate plays a crucial role in shaping the characteristics and biodiversity of a biome.

The correct answer is boreal forest. The boreal forest, also known as the taiga, is a Canadian biome that is dominated by evergreen trees. These trees are able to survive the harsh winter conditions with their needle-like leaves, which helps them conserve water and withstand cold temperatures. The boreal forest is characterized by its dense coniferous tree cover and is home to a variety of wildlife species adapted to this unique ecosystem.

The tundra is a biome characterized by extremely cold temperatures, permafrost, and a lack of trees. It is a vast, treeless landscape with low precipitation and short growing seasons. Spruce trees are not found in the tundra as they are adapted to temperate and boreal forests. Therefore, the statement "has spruce trees" does not describe the tundra.

The phrase "will meet the needs of present and future generations" best matches the concept of sustainability because it implies the ability to maintain and support the well-being of current and future generations without depleting or harming natural resources. It suggests a balance between meeting present needs and ensuring that resources are available for future generations to meet their needs as well. This concept aligns with the idea of sustainable development and responsible resource management.

Lemmings are the most representative animal of the tundra biome. Lemmings are small rodents that are well adapted to the harsh conditions of the tundra, such as cold temperatures and limited food sources. They play a crucial role in the ecosystem as they are a primary food source for predators like owls, foxes, and weasels. Lemmings are known for their cyclic population fluctuations, where their numbers increase rapidly and then decline dramatically. This population cycle has a significant impact on the tundra ecosystem and is an important characteristic of the tundra biome.

Grassland is the correct answer because it has the most fertile soil compared to the other biomes listed. Grasslands have deep, nutrient-rich soils that are ideal for plant growth. The grasses in these biomes have extensive root systems that help in nutrient absorption. Additionally, the frequent wildfires in grasslands contribute to the fertility of the soil by recycling nutrients back into the ground.

The tundra is characterized by a very low biodiversity due to its extreme cold temperatures and short growing season. The harsh conditions make it difficult for many plants to survive, and only plants with very short roots can exist in this area. The tundra is known for its vast stretches of low-lying vegetation such as mosses, lichens, and small shrubs that are adapted to withstand the cold and windy conditions. This limited plant diversity is a defining feature of the tundra biome.

Grassland is the correct answer because it is a biome known for its warm summer temperatures and high winds. Grasslands are characterized by vast open spaces covered with grasses and few trees. They experience hot summers with temperatures that can reach high levels, and the wind is a common feature due to the lack of trees to block it. This combination of warm temperatures and high winds is a defining characteristic of grassland biomes.

The correct answer is "All the above" because a biome refers to a large geographical area characterized by distinct climate, plants, and animals. A jungle, forest, and ecosystems are all examples of different types of biomes. Therefore, all of the options provided are alternative names for a biome.

The correct answer is Tundra. Tundra is a biome characterized by extremely cold temperatures, short growing seasons, and low-growing vegetation. Mosses and lichens are the main types of vegetation found in the tundra due to their ability to survive in harsh conditions. This biome is found in the Arctic and high mountain regions and is known for its frozen soil, strong winds, and limited plant diversity.

Coniferous forests are characterized by a layer of ferns and mosses on the forest floor. These forests are typically found in colder regions with long, snowy winters. The layer of ferns and mosses helps to retain moisture and provide a suitable habitat for various organisms. Additionally, the acidic nature of the soil in coniferous forests supports the growth of ferns and mosses. Therefore, the presence of a layer of ferns and mosses on the forest floor is a characteristic feature of coniferous forests.

The correct answer is Temperate Rain Forest. Photosynthesis is the process by which plants convert sunlight into energy. During winter, the availability of sunlight decreases due to shorter days and less direct sunlight. In temperate rain forests, the dense canopy of trees blocks much of the sunlight from reaching the forest floor even in the summer, and this effect is further amplified during the winter. Therefore, photosynthesis decreases rapidly during the winter in temperate rain forests.

Permafrost is a layer of permanently frozen soil found in the tundra. This frozen ground prevents trees from developing deep root systems necessary for their growth and stability. The shallow active layer above the permafrost only thaws during the short summer, making it difficult for trees to establish themselves in the harsh tundra environment.

In grasslands, evaporation may exceed the annual precipitation. This is because grasslands typically have low rainfall and high temperatures, which promote rapid evaporation. The lack of trees and dense vegetation in grasslands also means that there is less interception and transpiration, leading to a higher proportion of water being lost through evaporation. Additionally, the open and exposed nature of grasslands allows for greater exposure to wind, which further enhances evaporation rates. Therefore, it is likely that evaporation exceeds the annual precipitation in grasslands.
