Using GIS to visualise and analyse deforestation

This unit teaches pupils about tropical rainforest and taiga biomes. Pupils learn about its biotic and abiotic characteristics, the adaptations of plants and animals and the threats facing its biodiversity. The unit considers opposing views on protecting and exploiting resources.

Tropical rainforest and taiga biomes

chemical substances found in all biotic features which aid survival

when two or more biotic features depend on each other to survive

Match the keywords with their definitions.

The taiga has a __________ biodiversity compared to the tropical rainforest.

long, freezing winters make it difficult for many species to survive

species have 3-5 months to grow and reproduce before winter returns

the soil lacks nutrients, making it hard for plants to grow

fewer plants = less food for herbivores, which limits predators

The taiga has a low biodiversity for several reasons:

The nutrient cycle in the taiga is __________ due to cold temperatures and acidic soil. Most nutrients come from decomposing needles and limited organic matter.

In the high latitudes of the Northern Hemisphere

What type of trees dominate the taiga biome?

They have needle-like leaves and thick bark

How do trees in the taiga adapt to cold conditions?

Why is deforestation a major threat to the taiga?
