Terrestrial Biomes and Their Unique Adaptations in a Changing Climate

The video discusses terrestrial biomes, focusing on their global distribution, climate conditions, and how organisms adapt to these environments. It highlights the importance of temperature and precipitation in defining biomes and explains how nutrient availability affects plant and animal life. The video also explores how climate change can shift biome locations, using examples like the boreal forest. The session concludes with a practice exercise on explaining biome characteristics.

What is the primary factor that distinguishes a desert biome from a tropical rainforest?

• Temperature

• Precipitation

• Soil type

• Latitude

Which adaptation helps camels survive in desert conditions?

• Long legs for running

• Sharp claws

• Thick fur

• Humps for fat storage

What are the two defining characteristics of a biome?

• Soil type and latitude

• Temperature and precipitation

• Altitude and humidity

• Animal species and plant species

Where are temperate biomes typically located?

• Between 30 and 60 degrees latitude

• Near the equator

• At the poles

• Above 60 degrees latitude

Why is the soil in the tundra biome low in nutrients?

• Excessive plant growth depletes nutrients

• Permanent frost limits decomposition

• Frequent flooding washes away nutrients

• High temperatures prevent decomposition

What is a characteristic of the tropical rainforest's soil?

• Frozen year-round

• Nutrient-poor due to high competition

• Rich in nutrients

• Sandy and dry

Which biome is known for having high nutrient levels due to leaf litter decomposition?

• Desert

• Temperate forest

• Boreal forest

• Tundra

How does climate change affect the boreal forest biome?

• It causes the forest to move southward

• It results in more rainfall in the region

• It shifts the forest further north

• It increases the biodiversity of the forest

What is a predicted change for the boreal forest by 2100?

• Expansion into tropical regions

• Shift further north due to warming

• Reduction in size due to desertification

• Increase in coniferous tree species

What is the main reason for the northward shift of the boreal forest?

• Decreased sunlight

• Thawing of previously frozen soils

• Increased human activity

• Increased rainfall
