Is the soil in the chaparral:
1. High in nutrients
2. Shallow and of poor quality
3. Deep and loamy
Shallow and of poor quality
200
What is the difference between weather and climate?
Weather: the short-term changes in the atmosphere Climate: atmospheric changes over longer periods of time, usually 30 years or more.
200
The fennec fox, bilby, scorpion and meerkat have all adapted to life in which biome?

Name 3 biomes that experience low or very low rainfall
1. Polar
2. Tundra
3. Desert
4. Savanna
300
Name 2 ways animals have adapted physically to rainforest biomes
1. Camouflage
2. Reduced size to make it easier to move through the dense forest
3. Use of poison
4. Mimicry
300
Name 3 ways plants have adapted to life in a coniferous forest
1. Needles instead of leaves to conserve water
2. Cones instead of flowers to protect seeds from harsh weather
3. Evergreen to photosynthesize all year round
4. Sloped branches to keep snow off
5. Wide shallow roots to maximise water collection and for stability
300
Why is the overharvesting of trees such a significant threat to coniferous forests?
Because conifers are slow growing, with some species taking decades to mature
300

What are two ways mountains can influence the characteristics of a biome?
1. Altitude - air cools by 0.6 degrees every 100 metres
2. Rain shadow effect (orographic rainfall) - rainy on one side and dry on the other

Which biome creates good conditions for farming because the plants that grow there create fertile soils?
Temperate grasslands

In polar biomes, how does climate and soil quality influence the diet of animals?
Little sunlight for long periods, low temperature and poor quality soils result in few plants. Many animals have adapted by being carnivorous.
