Biomes

Question 1

Biomes

Answer 1

• A biome is an area classified according to the species that live in that location
• Scientists can define a biome by defining the temperature range, soil type, amount of light, and water that are peculiar to a location and create opportunities for particular species.

Question 2

Difference between Biomes and Ecosystems

Answer 2

Biomes are large ecological areas with specific climate and organisms, while ecosystems are smaller localized systems.

Question 3

Desert

Answer 3

• hot, arid ecosystem
• found in regions such as the Sahara
• little rainfall (less than 250 mm per year)
• -4 to 50 degrees celsius
• diverse flora (cacti - can survive as they are succulents) and fauna (camels - can store water for long periods of time) that are specially adapted to conserve water and withstand the harsh conditions

Question 4

Savanna Grasslands

Answer 4

• found in the southern hemisphere
• characterized by vast rolling grasslands and scattered trees
• average rainfall of 50-150cm
• average temperature of 20-30°C
• home to several tall grasses, scattered trees, and bushy vegetation, and animals such as zebras, giraffes, lions, elephants, and various bird species

Question 5

Temperate Grasslands

Answer 5

• found in North America, Eurasia, and South America
• features vast grasslands with few trees
• average rainfall of 300-600 mm
• average temperatures ranging from -20 to 30°C
• home to prairie grasses, wildflowers, and herbs such as buffalo grass, purple coneflower, and wild indigo
• large herbivores such as bison, pronghorns, and small mammals like prairie dogs and jackrabbits.

Question 6

Tropical Forests

Answer 6

• found near the equator
• characterized by high levels of biodiversity
• average rainfall of around 2500 mm per year
• average temperature of 25-27°C
• wide range of flora, including large trees, vines, and ferns
• wide range of fauna like monkeys, birds, snakes, and other small mammals

Question 7

Temperate Forests

Answer 7

• located in regions with moderate temperatures and precipitation
• featuring trees that lose their leaves during the winter season
• average rainfall of 750mm-1500mm
• temperatures ranging from -30°C to 30°C
• often home to plant and animal species such as oaks, maples, deer, bears, and wolves

Question 8

Woodland Forests

Answer 8

• located in temperate regions
• characterized by moderate rainfall
• average temperatures are 20-30 degrees celsius
• dominated by deciduous trees
• fauna such as deer, birds, and other small mammals can be found

Question 9

Tiago Forests

Answer 9

• located in Brazil
• characterized by its high biodiversity
• average rainfall of 2000-3000mm
• temperature range of 20-28°C
• lush, dense vegetation consisting of trees such as mahogany and Brazil nut
• diverse range of animals such as toucans, jaguars, monkeys and sloths

Question 10

Tundra

Answer 10

• found at the far northern regions of the Earth
• characterized by permafrost
• has extremely low temperatures (-56 degrees)
• little precipitation (150-250 mm per year)
• having low-growing plants like lichens, mosses, and small shrubs
• animals adapted to cold, like caribou, wolves, and polar bears

Question 11

Alpine

Answer 11

• found in high altitude mountain regions
• characterized by rocky terrain
• -12 to 10 degrees celsius
• 300mm per year
• home to hardy plant species like mosses, lichens, and alpine flowers
• wildlife such as mountain goats, marmots, and birds adapted to survive in the harsh conditions.

Question 12

Spatial Distribution of Biomes across the Earth

Answer 12

• The spatial distribution of different biomes across the world varies according to their climatic conditions.
• The north mainly consists of tundra and polar ice cap.
• The south mainly consists of polar ice cap.
• The east and west have a variety of different biomes, including but not limited to taiga, temperate grassland, tropical seasonal forest, temperate deciduous forest, and subtropical desert.

Question 13

What is the relationship between biomes and climate

Answer 13

• The relationship between biomes and climate is highly interconnected
• Climate, which includes factors such as temperature, precipitation, and sunlight, plays a fundamental role in determining the types of plants and animals that can survive and thrive in a particular region
• Different biomes have adapted to specific climatic conditions over time, resulting in unique ecological communities
